Obtaining data with a large P-value.d. Using a large level of significance, α.e. Using a small level of significance, α
If we have a sample of size 100 with sample mean breaking strength of 975 pounds from a population of rope with standard deviation 200 pounds and we wish to run a hypothesis test with this data to see if the population mean breaking strength is less than 1000 pounds, what is the P-Value of our data? 2P(Z<1.25) P(Z>1.25) P(Z>2.5) P(Z<1.25) NONE OF THE OTHERS
A fast-food restaurant claims that a small order of french fries contains 120 calories. A nutritionist is concerned that the true average calorie count is higher than that. The nutritionist randomly selects 35 small orders of french fries and determines their calories. The resulting sample mean is 155.6 calories, and the pp-value for the hypothesis test is 0.00093. Which of the following is a correct interpretation of the p-value? A)If the population mean is 120 calories, the p -value of 0.00093 is the probability of observing a sample mean of 155.6 calories or more. B) If the population mean is 120 calories, the p -value of 0.00093 is the probability of observing a sample mean of 155.6 calories or less. C)If the population mean is 120 calories, the p -value of 0.00093 is the probability of observing a sample mean of 155.6 calories or more, or a sample mean of 84.4 calories or less. .D)If the population mean is 155.6 calories, the p -value of 0.00093…

So, she polled 150 people and asked them their occupation and which soda they preferred. The data are below. Conduct an appropriate statistical test using an alpha level of .05.

If the level of significance in a hypothesis test is 1 %, what would the p-value have to be for failing to reject the null hypothesis? a. equal to 0.005 b. less than .01 c. greater than .01
If, in a one-tail hypothesis test where H0 is only rejected in the upper tail, the p-value=0.6792 and ZSTAT=−0.47,what is the statistical decision if the null hypothesis is tested at the 0.07 level of significance? What is the statistical decision? Since the p-value is Less than or Greater than or equal to a= , Reject , Do not reject H0.
With H1: p < 0.32, a test statistic is z = -1.23. Use a 0.01 significance level to find the P-value, and state the conclusion about the null hypothesis.
Given the following null and alternative hypotheses H0: µ1 - µ2 = 0 HA: µ1 - µ2 ≠ 0 and the following sample information Sample 1 Sample 2 n1 = 125 n2 = 120 s1 = 31 s2 = 38 x1 = 130 x2 = 105 Develop the appropriate decision rule, assuming a significance level of 0.05 is to be used. Test the null hypothesis and indicate whether the sample information leads you to reject or fail to reject the null hypothesis. Use the test statistic approach.
The following hypothesis test is to be conducted.h0: Median ≤ 150ha: Median > 150A sample of 30 provided 22 observations greater than 150, 3 observations equal to 150, and 5 observations less than 150. Use a = .01. What is your conclusion?
Given that the P-value for the hypothesis test is 0.000 when rounded to three decimal places, what do you conclude? What do the results indicate about the rule that women and children should be the first to be saved?
Assuming that all the assumptions of statistical hypothesis testing are met, based on the z-score of 1.96 and the sample size of 200, the appropriate conclusion for this test would be? a) P-value is under .05, we would reject the null hypothesis b) P-value is over .05, we would failed to reject the null hypothesis c) P-value is under .05, we would fail to reject the null hypothesis d) P-value is over .05, we would reject the null hypothesis
Test the null hypothesis H0 : β1 = β2 against the alternative H1 : β1 < β2 at 1% significance level.
