Researchers have claimed that the average number of headaches per student during a
semester of Statistics is 19. Statistics students believe the average is not equal to 19. In a
sample of n = 14 students the mean is 22 headaches with a deviation of 2. Which of the
following represent the null and alternative hypotheses necessary to test the students' belief?
Select one:
O Ho: H<19 vs. Hr. u = 19
O Ho: u = 19 vs. Hr: u# 19
OHo u= 19 vs. Hr. u< 19
O Ho: u= 19 vs. Hr: u > 19

We suspect that the mean number of hours worked per week by college graduates, u, is different from 40 hours and wish to do a statistical test. We select a random sample of college graduates employed full-time and find that the mean of the sample is 44 hours and that the standard deviation is 4 hours. Based on this information, answer the questions below.arrow_forwardA test of sobriety involves measuring the subject's motor skills. Twenty randomly-selected sober subjects take the test and produce a mean score of 41.0 with a standard deviation of 3.7. At the 0.01 level of significance, test the claim that the true mean score for all sober subjects is equal to 35.0. Use the traditional method of testing hypotheses. The results for the test turn out to be: Ho: H = 35.0. H1:µ/35.0. Test statistic: t 7.252. Critical values: t = -2.861, 2.861. Reject Ho. There is sufficient evidence to warrant rejection of the claim that the mean is equal to 35.0. If a defense attorney argues the results are not valid because the sample size was too small, is his argument valid here? Yes, because the t-test is not as powerful as the z-test. No, because we rejected the null hypothesis. Yes, because we rejected the null hypothesis. O No, the sample size is never an issuc. O We need more information to answer.arrow_forward
- It is suggested that the mean one-day travel expense by tourists in Moscow is $500 (assume all one-day travel expenses in Moscow are approximately normally distributed). In a random sample of 16 Moscow tourists, the sample mean one-day travel expense was $482 with a sample standard deviation s = 22.5. Our goal is to test whether or not the mean one-day travel expense is $500 or not. Real life conclusion? A) We lack evidence to suggest that the mean one-day travel expense for Moscow tourists is not $500. B) The mean one-day travel expense is $4820 C) The mean one-day travel expense is $500 D) Evidence strongly suggests that the mean one-day travel expense for Moscow tourists is not $500.arrow_forwardAccording to the College Board, scores on the math section of the SAT Reasoning college entrance test for the class of 2010 had a mean of 516 and a standard deviation of 116.

For healthy adults, the red blood cell volume mean is about µ = 28 ml/kg with a standard deviation of 4.75ml/kg. Red blood cells volume that is too low or too high can indicate a medical problem. Suppose he does a hypothesis test with a significance level of 0.01. Roger has had seven blood tests and the red blood cell volumes were: 32 25 41 35 30 37 29 Roger’s null hypothesis is that his blood tests are normal and that his alternative hypothesis is that something is wrong. Symbolically, the null and hypotheses are as follows Ho: µ = 28 ml/kg and Hi: µ ≠ 28 ml/kg What value of the test statistic (z) should he report?
