120.A restaurant that bills its house account monthly is concerned that the average monthly bill exceeds \$200 per account. A random sample of twelve accounts is selected, resulting in a sample mean of \$220 and a standard deviation of \$12. The t-test is to be conducted at the 5% level of significance.Given the following printout, what can you determine?A. The alternate hypothesis is μ200B. You should accept the null hypothesis at the 0.05 level of significance.C. There is less than a 1% chance of getting these results if the null hypothesis is true, so you have very strong evidence to suggest that the average bill is more than \$200.D. There is less than a 1% chance of getting these results if the null hypothesis is true, so you have very strong evidence to suggest that the average bill is less than \$200.E.The alternate hypothesis is μ200 and you should accept the null hypothesis at the 0.05 level of significance.121.i. Two examples of a hypothesis are:1) mean monthly income from all sources for senior citizens is \$841 and2) twenty percent of juvenile offenders ultimately are caught and sentenced to prison.ii. Hypothesis testing is a procedure based on sample evidence and probability theory to decide whether the hypothesis is a reasonable statement.iii. Since there is more variability in sample means computed from smaller samples, we have more confidence in the resulting estimates and are less apt to reject null hypothesis. A. (i), (ii) and (iii) are all correct statementsB. (i) is a correct statement but not (ii) or (iii).C. (i) and, (iii) are correct statements but not (ii).D. (i) and, (ii) are correct statements but not (iii).E. All statements are false122.i.
