We want to conduct a hypothesis test of the claim that the population mean score on a nationwide examination in biology isdifferent from 511. So, we choose a random sample of exam scores. The sample has a mean of 490 and a standard deviation of 78.For each of the following sampling scenarios, choose an appropriate test statistic for our hypothesis test on the population mean.Then calculate that statistic. Round your answers to two decimal places.(a) The sample has size 85, and it is from a non-normally distributed population with a known standard deviationof 77.OZ =0Ot=O It is unclear which test statistic to use.(b) The sample has size 12, and it is from a normally distributed population with an unknown standard deviation.O Z=Ot=O It is unclear which test statistic to use.X

A century ago, the average height of adult women in the United States was 63 inches. Researchers believe that the average might be greater today. A random sample of 40 adult women was selected from the population. The sample had mean 64.2 inches and standard deviation 2.9 inches. Assuming all conditions for inference are met, the researchers will perform an appropriate hypothesis test to investigate their belief. Which of the following is the correct test statistic for the hypothesis test? A t = 63-64.2 2.9 63-64.2 2.9 t 3= 63-64.2 29 40 64.2-63 t 3= 2.9 64.2-63 t = 2.9 US 1 DELL 么 & %24 %23 || E.
A real estate agent claims that mean household incomes in Fairfax and Arlington are equal. Draw 32 residents randomly from Fairfax neighborhood we found the average income is $82,750 with population standard deviation $2900; while from 30 Arlington residents, the average income 81,200 with with population deviation $2225. If we go against the claim What is the p value ?
We want to conduct a hypothesis test of the claim that the population mean score on a nationwide examination in biology is different from 478. So, we choose a random sample of exam scores. The sample has a mean of 488 and a standard deviation of 73. For each of the following sampling scenarios, choose an appropriate test statistic for our hypothesis test on the population mean.

According 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. Assume that they are roughly normal.One of the quartiles of the scores from the math section of the SAT Reasoning test is 438. The other quartile is _______.
A recent report claims that Americans spend an average of $11 per day on lunch. You believe that people who live in Philadelphia, PA spend significantly less on lunch per day than that. In order to test this, you randomly sampled n=100 Philadelphia residents and asked them how much they spend on lunch everyday. The sample average of these respondents was $10.92 with a sample standard deviation of $1.07. If you want to test the null hypothesis that H0: mean=11 vs Ha: mean <11.what is the value of the test statistic?
We want to conduct a hypothesis test of the claim that the population mean score on a nationwide examination in anthropology is different from 493. So, we choose a random sample of exam scores.

In the past, the mean age of consumers of a product was 38 years. Recently the product has been drastically changed. In order to determine whether there has been a change in the mean age of the product consumers, a sample of 16 consumers is selected. The mean age in the sample is 33 years and the standard deviation in the sample is 10 years. Let u = the mean age of the current product (Problem Set #7) consumers. The value of the test statistic is Oa. -2.00 O b.-1.60 OC .0.8 O d. 4.21
