1) Find the standardized t test 2) Find the P-values 3) Decide whether to reject or fail to reject the null hypothesis. 4) Interpret the decision in the context of the original claim.

XY company is being charged with discrimination in its overtime salary payment. What hypothesis is being tested if a court commits a type I error by finding the company guilty? (A) The company is not guilty B the company is always guilty C) The company is guilty (D) none of the choices

5) In order to determine whether or not a driver's education course improves the scores on a driving exam, a sample of 6 students were given the exam before and after taking the course. The results are shown below.   Student Score (Before the Course) Score (After the Course) 1 83 87 2 89 88 3 93 91 4 77 77 5 86 93 6 79 83 A) Determine the null and alternative hypotheses. B) Compute the test statistics. C) At 95% confidence using the p-value approach, test to see if taking the course actually increased scores on the driving exam.

Suppose that people were asked "would you leave your current job to make more money at a new job?", and the following table with the responses to the question as well as the generation that the subject belonged to was constructed: "Leave Job for More Money"     "Baby Boomer"     "Millenial" Yes                                              115                        175 No                                              165                        185 If a Test of Independence is performed on this table to determine if "Generation" and "Willingness to Leave a Job for More Money" are independent of each other, then calculate the value of the Test Statistic (TS) that you would get when running this hypothesis test. Round off your answer to the third decimal place: The TS in this problem, rounded off as instructed, is:

1 - find the p-value 2 - reject or fail to reject null hypothesis?

Part C, D and E please, Thank You! D) What is the null hypothesis? E) Reject the null hypothesis because the P-value is greater than the significant level, a Reject the null hypthosesis because the P-value is less than or equal to the significant level, a Fail to reject the null hypothesis because the P-value is greater than or equal to the significant level, a Fail to reject the null hypothesis because the P-Value is greater than the significant level, a

In a hypothesis test, a Type l| error occurs when: O 1) a false null hypothesis is rejected O 2) a true null hypothesis is not rejected 3) a false null hypothesis is not rejected O 4) a true null hypothesis is rejected

Describe the four possible outcomes when conducting a hypothesis test.

According to a​ study, approximately​ 60% of US adults believe that they have​ achieved, or are within reach​ of, the​ "American Dream"​ (that is, home ownership and financial​ stability). Now consider a random sample of 400 US adults. What is the probablity that over​ 65% of the sampled adults believe they have reached or are optimistic about reaching the American​ Dream?    NEED ANSWER! No explanattion please

Laura spends an average of 1.5 hours doing her homework. After organizing her desk, Laura thinks she will spend less time doing her homework. She wants to the test that claim. Please show ALL work and explanations! Thank You! A.)State the null hypothesis. B.)State the alternative hypothesis
