A​ true/false test has 100 questions. Suppose a passing grade is 60 or more correct answers. Test the claim that a student knows more than half of the answers and is not just guessing. Assume the student gets 60 answers correct out of 100. Use a significance level of 0.05. Steps 1 and 2 of a hypothesis test procedure are given below. Show step​ 3, finding the test statistic and the​ p-value and step​ 4, interpreting the results. Step​ 1: H0​: p=0.50 Step​ 1: Ha​: p>0.50   Step​ 2: Choose the​ one-proportion z-test. Sample size is large​ enough, because np0 is 100​(0.5)=50 and n1−p0 ​= 100​(.5) ​= 50​, and both are more than 10. Assume the sample is random. Step​ 3: Compute the​ z-test statistic, and the​ p-value.

Describe type I and type II errors for a hypothesis test of the indicated claim. A shoe store claims that no more than 25% of its new customers will return to buy their next pair of shoes. Describe the type I error. Choose the correct answer below. 16 OA. A type I error will occur when the actual proportion of new customers who return to buy their next pair of shoes is at least 0.25, but you reject Ho: p≥ 0.25. B. A type I error will occur when the actual proportion of new customers who return to buy their next pair of shoes is no more than 0.25, but you fail to reject Ho: p ≤ 0.25. C. A type I error will occur when the actual proportion of new customers who return to buy their next pair of shoes is at least 0.25, but you fail to reject Ho: p≥ 0.25. D. A type I error will occur when the actual proportion of new customers who return to buy their next pair of shoes is no more than 0.25, but you reject Ho: p≤0.25. Describe the type II error. Choose the correct answer below. O A. A type II…

A college counselor wants to perform the hypothesis test H0 : p = 0.50, Ha: p > 0.50, where p is the proportion of undergraduate students who eat breakfast. In a sample of 446 students, 246 ate breakfast.  What is the P-value for this hypothesis test?   a .0147 b .9853 c .552 d .448

What are the correct answers?

The critical boundaries for a hypothesis test are z = +1.96 and -1.96. If the z-score for the sample data is z =-1.90, what is the correct statistical decision?​     ​Reject H0   ​Fail to reject H1   ​Reject H1   ​Fail to reject H0
