Suppose we want to examine the tips earned for waiters in Clark County compared to the entire population of waiters in Nevada. We know the population variance. We are unsure which group would have higher tips.

a. State the null and alternative hypothesis in symbolic form.

b. State the null and alternative hypothesis in word form.

c. Which test should we use?

Alpha is set at .05. Here are the test statistics: p = .07, 95% CI = [-.01, .04].

d. What does the statistic above indicate for the hypothesis?

11. The correct interpretation of 95% confidence is (Circle one): a) We can be 95% confident that the interval includes the sample mean. b) 95% of all possible population means will be included in the interval. c) 95% of the possible sample means will be included in this interval. d) The method used to get the interval, when used over and over, produces intervals which include the true population mean 95% of the time. 12.

1. .We are interested in the average dollar amount lost by victims by burglary. The National Insurance Association has reported that the mean dollar amount lost by victims of burglary is $2,222. Assume that this is the population mean. We believe that the true population mean loss is different from this. Formally state the null and research hypotheses we would test to investigate this question. What if we believed the dollar amount to be higher? 2. A friend of yours...

suppose a random sample of 25 is taken from a population that follows a normal distribution with unknown mean and a known variance of 144. Provide the null and alternative hypothesis necessary to determine if there is evidence that the mean of the population is greater than 100. Using the sample mean ybar as the test statistic and a rejection region of the form {ybar>k} find the value of k so that alpha=.15 Using the sample mean ybar as the...

2. In a study examining the effect of caffeine on reaction time, Liguori and Robinson (2001) measured reaction time 30 minutes after participants consumed one 6-ounce cup of coffee and they used standardized driving simulation task for which the regular population averages μ = 415 msec. The distribution of reaction times is approximately normal with σ = 40. Assume that the researcher obtained a sample mean of M = 400 msec for the n = 36 participants in the study....

textRequest reports that adults 18–24 years old send and receive 128 texts every day. Suppose we take a sample of 25–34 year olds to see if their mean number of daily texts differs from the mean for 18–24 year olds reported by TextRequest. a. State the null and alternative hypotheses we should use to test whether the popu-lation mean daily number of texts for 25–34 year olds differs from the population daily mean number of texts for 18–24 year olds....

1) The value of the z-score that is obtained for a hypothesis test is influenced by several factors. Some factors influence the size of the numerator of the z-score and other factors influence the size of the standard error in the denominator. For each of the following, indicate whether the factor influences the numerator or denominator of the z-score and determine whether the effect would be to increase the value of z (farther from zero) or decrease the value of...

Does our cognitive capacity change as we age? Researchers have noted a change in cognitive functioning as people age (Bartus, 1990). However, the results from other research suggests that the antioxidants in foods such as blueberries may reduce and even reverse these age-related declines. You decide to conduct your own study using a related-samples (within-subjects) design, to determine if a blueberry supplement can change cognitive capacity in older adults. You will use an alpha level = .05, and choose to...

Question #5 – Chi Squared Testing This is Part B I) Milk products are an important source of calcium and vitamin D, nutrients that play an essential role in maintaining bone health and preventing osteoporosis. However, most milk products also contain lactose, which a large proportion of the world’s population has trouble digesting. http://www.osteoporosis.ca/wp-content/uploads/2017-05-31-COPING-Lactose-Intolerance-FINAL.pdf In fact, it has been estimated that seven million Canadians suffer from lactose intolerance. There are many factors affecting how populations adapt and react to lactose...
