The average salary for American college graduates is $44,300. You suspect that the average is differentfor graduates from your college. The 61 randomly selected graduates from your college had an averagesalary of $44,099 and a standard deviation of $4,460. What can be concluded at the a = 0.10 level ofsignificance?a. For this study, we should useSelect an answerb. The null and alternative hypotheses would be:Họ:vSelect an answerH: ? vSelect an answerc. The test statistic(please show your answer to 3 decimal places.)d. The p-value =(Please show your answer to 4 decimal places.)e. The p-value isvathe null hypothesis.f. Based on this, we should Select an answerg. Thus, the final conclusion is that ...O The data suggest that the population mean is not significantly different from 44,300 at a =0.10, so there is statistically insignificant evidence to conclude that the population meansalary for graduates from your college is different from 44,300.The data suggest that the sample mean is not significantly different from 44,300 at a =0.10, so there is statistically insignificant evidence to conclude that the sample mean salaryfor graduates from your college is different from 44,099.O The data suggest that the populaton mean is significantly different from 44,300 at a = 0.10,so there is statistically significant evidence to conclude that the population mean salary forgraduates from your college is different from 44,300.h. Interpret the p-value in the context of the study.O If the population mean salary for graduates from your college is $44,300 and if another 61graduates from your college are surveyed then there would be a 72.57% chance that thepopulation mean would either be less than $44,099 or greater than $44,501.O There is a 72.57% chance of a Type I error.O lf the population mean salary for graduates from your college is $44,300 and if another 61graduates from your college are surveyed then there would be a 72.57% chance that thesample mean for these 61 graduates from your college would either be less than $44,099 orgreater than $44,501.O There is a 72.57% chance that the population mean salary for graduates from your college isnot equal to $44,300.i. Interpret the level of significance in the context of the study.O If the population mean salary for graduates from your college is $44,300 and if another 61graduates from your college are surveyed then there would be a 10% chance that we wouldend up falsely concuding that the population mean salary for graduates from your college isdifferent from $44,300.O lf the population population mean salary for graduates from your college is different from$44,300 and if another 61 graduates from your college are surveyed then there would be a10% chance that we would end up falsely concuding that the population mean salary forgraduates from your college is equal to $44,300.O There is a 10% chance that your won't graduate, so what's the point?O There is a 10% chance that the population mean salary for graduates from your college isdifferent from $44,300.

A national publication reported that a college student living away from home spends, on average, no more than $15 per month on laundry. You believe this figure is too low and want to disprove this claim. To conduct the test, you randomly select 17 college students and ask them to keep track of the amount of money they spend during a given month for laundry. The sample produces an average expenditure on laundry of $19.34, with a population standard deviation of $4.52. Use these sample data to conduct the hypothesis test. Assume you are willing to take a 10% risk of making a Type I error and that spending on laundry per month is normally distributed in the population

If the population standard deviation is $8.36, test the claim that the mean cost of a taxicab ride in New York City is less than $15.00. (a) State the null and alternative hypothesis. (b) By hand, find the test statistic z-score. Round to two decimal places. (c) Sketch the sampling distribution labeling the test statistic found in part (b) and compare it to the critical value z-score found in the previous question to make a decision to either reject or fail to reject the null hypothesis.

Do political science classes require less writing than history classes? The 43 randomly selected political science classes assigned an average of 14.6 pages of essay writing for the course. The standard deviation for these 43 classes was 5.9 pages. The 52 randomly selected history classes assigned an average of 15.4 pages of essay writing for the course. The standard deviation for these 52 classes was 4.5 pages. What can be concluded at the a= 0.01 level of significance?
