What Is The Value Of P In The Linear Equation – Value is the minimum significance level at which we can reject the null hypothesis. Assuming the null hypothesis is true, the probability of producing test statistics that confirm the rejection of the null hypothesis.
When performing a statistical test with a certain significance level (α), we compare the observed test statistic with some other significant value. For example, we can reject H
What Is The Value Of P In The Linear Equation
At the 1% significance level.” The problem with this ‘classical’ approach is that it does not give us a complete picture of the strength of the evidence against the null hypothesis.
Find The P Value From A T Value
Estimates are given by the probability below the test statistic for left-tailed tests. In the case of right-tailed tests, the probability above the test statistic is given
However, if the test is two-tailed, this value is the sum of the probabilities in the two tails. We begin by determining the probability that the test statistic lies below a negative value. After this, we add it to the horizontal probability above the test value.
θ represents the probability of getting a head when tossing a coin. Suppose we toss a coin 200 times and come up heads in 85 out of 200 trials. Test the following hypothesis at 5% level of significance.
“There is strong evidence against the assumption that the coin is genuine. Therefore, we conclude that the coin is genuine.

That doesn’t mean it’s true. This means that there is insufficient evidence to justify H’s rejection
Question A CFA candidate performs a statistical test about the mean value of a random variable. Given a 5% significance level, determine the p-value. A. 1.39%. B. 2.78. C. 2.78%. Solution C. $$ text P-text= P(Z > 2.2) = 1 – P(Z < 2.2) = 1.39% × 2 = 2.78 % $$ is the correct answer. This is a two-tailed test.) Interpretation: The P-value (2.78%) does not reach the significance level (5%). Therefore, we have enough evidence to reject H0. In fact, the evidence is so strong that we reject H0 at the 4% and 3% significance levels. However, at the 2% or 1% significance levels, we do not reject H0 because the p-value exceeds these values.

So please help. I use the video to prepare for the CFA Level II exam. Videos highlight reading material, explain concepts, and provide more context for a particular concept. The bright illustrations are fun and a welcome break from some of the dry content. I usually watch the video before diving into an in-depth reading, it’s a great way to not be overwhelmed by the content while you’re watching the reading.
A major software provider. James sir explained the concept very well and you can understand them by understanding instead of memorizing it. Thanks! Thanks, I came across this at the right time of my CFA program.
It explains well and gives a good understanding of the topics in a short span of time. I was glad to have Professor Forgen’s lectures.
I completed my FRM1. Now use my FRM2 programs. Professor Forgen is brilliant. He provides such good information and suggestions. Above all it makes learning fun. A big thank you to Professor Forjan. 5 stars everywhere!

Professor James’ videos are excellent for understanding the principles behind Financial Engineering/Financial Analysis. The videos are better than any other video I have searched on YouTube for giving a detailed explanation of some concepts like portfolio theory, CAPM and price arbitrage theory. Seeing these cleared most of my mind. Very good advice.

The p-value is the probability of finding a test result as extreme as the observed result, under the assumption that the null hypothesis is true. (difficult to understand easily)
Absurdity is the explanation of the world we want to explore (whether couponing increases sales or not). In this world, we believe that offering coupons does not increase sales. We collect data samples (representing the population) and obtain our statistics (mean, variance, mean, etc.). The p-value is the probability that the world we wish to explore will produce the number obtained from our sample collection. More information in the image below.
The p-value only tells us whether our null hypothesis is true or not, so we can reject it or fail to reject it. However, we should not be satisfied if p < alpha (typically 0.05) and consider type I and type II errors. Type I error (= alpha) is the probability of rejecting the null hypothesis when it is true. Type II error is the probability of accepting (or not rejecting) a null hypothesis when it is false.
A Type I error may have opportunity costs, but a Type II error is more harmful. Consider the development of medicine. Refusal of a treatment that could work resulted in the company losing money on its investment. However, taking medications that don’t work puts people’s lives at risk. I refer to Type I and Type II errors as producer risk and consumer risk. So the power of the test is also important (power of the test = 1-type II error = probability of rejecting the null hypothesis when it is false). More on experimental power in Figure 2.

Intervals are interpreted as follows: (1) If we collect 100 samples (and create a confidence interval for the estimate for each sample), the frequency of these confidence intervals containing the true statistical value (for example, the population mean) is controlled. . Session 1-
. (2) When we calculate a confidence interval, we say that in future tests, the true statistical value will lie within that confidence interval (this is equivalent to doing the multiple iterations just discussed in (1).

The File That Made Me a Data Scientist JobsSpoiler Alert: It’s surprisingly easy (and free) to do When you perform a statistical test, the p-value helps you determine the significance of your results relative to a null hypothesis.
The null hypothesis (H0) states that there is no relationship between the two variables under study (one variable does not affect the other). He described the results as random and not significant in terms of supporting the hypothesis under investigation. So, the null hypothesis assumes that whatever you tried didn’t happen.
The alternative hypothesis (Ha or H1) is what you would believe if the null hypothesis were not true.
Find The Value Of A, For Which Point P (a/3 , 2) Is The Mid Point
The alternative hypothesis states that the independent variable affects the dependent variable, and the results are significant in terms of supporting the hypothesis under investigation (ie, not due to chance).
A p-value, or numerical probability value, is a number that describes how likely it is that your statement is true by chance (that is, the null hypothesis is true).
The probability of the result occurring by chance is low, and you need strong evidence to reject the null hypothesis.
Remember, the p-value does not tell you whether the null hypothesis is true or false.
