When the p value > alpha null hypothesis is not rejected so the option d will be answer that is p value >alpha

When the null hypothesis is rejected: Op< alpha p > beta p < beta p > alpha
A statistician was testing the following hypothesis: Ho: u < 501.3 The p-value approach was to be used with a sigma of 32.2. A sample of size of 51 gave a sample mean of 505.2. Find the p-value to 4 decimal places.
Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. Ho: p = 0.65 versus H : p<0.65 n= 150, x= 87, a = 0.01 Is npo (1-po) 2 10? Ο Νο Yes Use technology to find the P-value. P-value = (Round to three decimal places as needed.)
A research team wishes to test the null hypothesis Ho: p = 0 at a = 0.005 against the alternative Hz: p > 0 using Fisher's transformation of the Pearson product moment correlation coefficient as the test statistic. They have asked their consulting statistician for a sample size n such that B = 0.01 when p = 0.25. What is this value? This problem is worth 40 points.
n = 36 Ho: u 220 x = 18 Ha: u < 20 S= 12 If the test is done at a .05 level of significance, the null hypothesis should not be rejected be rejected Not enough information is given to answer this question. None of the other answers are correct. OO
What is the decision rule when using the p-value approach to hypothesis testing? Multiple Choice Do not reject H0 if the pvalue < 1-α. Reject Ho if the p-value > a Do not reject H0 if the p-value > 1-α Reject Ho if the p-value < α.

9 Test the null hypothesis Ho : u = 3.0against the alternative hypothesis HA: U < 3.0 , based on a random sample of 25 observations drawn from a normally distributed population with ū = 2.8 and o = 0.70. a) What is the value of the test statistic? Round your response to at least 3 decimal places. Number b) What is the appropriate p-value? Round your response to at least 3 decimal places. Number c) Is the null hypothesis...

One characteristic measured about high schools is the percent free lunch, which is the percentage of the student body that is eligible for free and reduced-price lunches. The top 100 schools, grouped according to their percent free lunch, is as follows.
