Casey is a statistics student who is conducting a one-sample ?z‑test for a population proportion ?p using a significance level of ?=0.05α=0.05. Her null (?0H0) and alternative (??Ha) hypotheses are
?0:???:?=0.094≠0.094H0:p=0.094Ha:p≠0.094
The standardized test statistic is ?z = 1.20. What is the ?P-value of the test?
A p-value of 0.02 means that you must:
a. Reject the null hypothesis
b. Accept the null hypothesis
c. Go back to the drawing board because you shouldn’t get a result higher than 0.05
d. Recode your data so you make sure to get statistically significant results
A significance level for a hypothesis test is given as α = 0.01 α=0.01 . Interpret this value. The probability of making a Type I error is 0.01. There is a 1% chance that the sample will be biased. The probability of a Type II error is 0.01. The smallest value of α α that you can use and still reject H 0 H0 is 0.01.

- Cindy is a server at a local restaurant who makes, on average, $58 in tips per daytime shift. Cindy thinks she will make more if she moves to the nighttime shift. Her manager will choose five random nighttime shifts for Cindy to work. Cindy plans to conduct a significance test on the hypotheses H0: mu = 58; Ha: mu > 58 at the alpha = 0.05 level, where is the true mean amount of tips Cindy will make working nighttime shifts. Are the conditions for performing the test met? No, the 10% condition is not met. No, the sample size is too small, and a Normal distribution cannot be assumed. Yes, all conditions are met for performing a significance test about the mean. Yes, only the random condition must be met in order to perform a significance test. No, there is no way the manager could choose a random sample of shifts to work.arrow_forwardReports say that the mean birth weight of babies of European heritage is 3.5 kg.
