Food inspectors inspect samples of food products to see if they are safe. This can be thought of as a hypothesis test with the following hypotheses. Ho: the food is safe Ha: the food is not safe The following is an example of what type of error? The sample suggests that the food is not safe, but it actually is safe. type I type II not an error

The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject Ho when the level of significance is (a) a = 0.01, (b) a = 0.05, and (c) a = 0.10. P=0.1162 (a) Do you reject or fail to reject H, at the 0.01 level of significance? O A. Reject H, because the P-value, 0.1162, is greater than a = 0.01. O B. Reject H, because the P-value, 0.1162, is less than a= 0.01. O C. Fail to reject Ho because the P-value, 0.1162, is less than a= 0.01. O D. Fail to reject H, because the P-value, 0.1162, is greater than a = 0.01. (b) Do you reject or fail to reject H, at the 0.05 level of significance? O A. Fail to reject H, because the P-value, 0.1162, is less than a = 0.05. O B. Reject Họ because the P-value, 0.1162, is greater than a = 0.05. O C. Fail to reject Ho because the P-value, 0.1162, is greater than a = 0.05. O D. Reject H, because the P-value, 0.1162, is less than oa = 0.05. (c) Do you reject or fail to reject Ho at the 0.10 level of significance? O A. Reject H,…

Which statistical inference technique should be used to answer the following statistical question? A shoe company believes the average foot size of its customers is 9.25 feet. They took a random sample of 100 customers' foot sizes. A confidence interval for the population proportion. A hypothesis test for the population mean. A confidence interval for the population mean. A hypothesis test for the population proportion. A hypothesis test for the difference between two population means.

This is a _______ tailed test. The correct statistical test to use for this problem is: Hypothesis testing: The last part of the null and alternative hypotheses are: What is/are the critical values for this problem? What is the obtained statistic for this problem? The effect size for this problem is _______.

For a hypothesis test, if the p-value for the test statistic is less than the significance level, which one of the following is a correct conclusion? Group of answer choices Reject the null hypothesis. There is enough evidence to conclude the alternative hypothesis is true. Fail to reject the null hypothesis. There is enough evidence to conclude the null hypothesis is true. Reject the null hypothesis. There is not enough evidence to conclude the alternative hypothesis is true. Fail to reject the null hypothesis. There is not enough evidence to conclude the alternative hypothesis is true.

Which of the following is the name for the statistical hypothesis that describes no change, or nothing expected?   Type I error    Null hypothesis    Type II error    Alternative hypothesis

What does it mean when sample results are statistically significant?

You play roulette and observe the ball land in the 1st dozen (i.e., 1-12) 5 times out of 5 spins. You want to perform a test to determine if the wheel is fair. State the null and alternative hypothesis. What is the p-value of this test? For ? α =.05 significance level, what do you conclude?

Test the claim that the proportion of men who own cats is smaller than the proportion of women who own cats at the .025 significance level. The null and alternative hypothesis would be: Ho MMF Ho: PM = PF H₁: MMF O H₁: PM > PF O The test is: two-tailed right-tailed O The test statistic is: Based on a sample of 60 men, 25% owned cats Based on a sample of 40 women, 40% owned cats The p-value is: Ho: M = μF H₁: UM
