Thanks. Why is Kathy's score considered better-is it because it is a posituve score? What does the Z score represent in this case?
ath ess Most Watched Ani... A pharmaceutical company claims their new diabetes medication results in less variance in a patient's glucose level than if the patient were on no medication at all. An endocrinologist wishes to test this claim. She divides participants randomly into two groups. Group A consists of 20 diabetics who received the medication; group B consists of 26 diabetics who received a placebo. After two weeks, the blood sugar level of each patient in each group was measured with the following results (in mg/dL): Group A: 77.8, 229.4, 199.9, 110.1, 180.2, 116.1, 139.7, 171.1, 37.4, 158.1, 88.4, 195.5, 246.1, 142.4, 178.1, 105.5, 179.6, 146.1, 78.8, 123.7 Group B: 124.5, 130.1, 136, 162.8, 113.4, 72.8, 142.6, 50.3, 179.8, 197, 230, 194.3, 171, 109.3, 114.4, 107.5, 114.7, 195.3, 127.7, 126.4, 85.6, 166.7, 182.3, 113.5, 216.7, 162.8 Ho: Perform a hypothesis test using a 6% level of significance to test the pharmaceutical company's claim.

Question 11 A sample of adults was asked to indicate the amount of money, in dollars, they would be willing to spend on a wedding gift. When a histogram was constructed based on the responses given by each adult, most of the dollar amounts were on the larger side, with only a few dollar amounts on the smaller side. Two measures of center were calculated for this sample: $150 and $279. One of these measures is the mean, and the other is the median. Which measure must be the mean? The mean is $279 because the distribution of dollar amounts would be skewed to the left. The mean is $279 because the distribution of dollar amounts would be skewed to the right. The mean is $150 because the distribution of dollar amounts would be skewed to the left. The mean is $150 because the distribution of dollar amounts would be skewed to the right.
A study was undertaken to see how accurate food labeling for calories on food that is considered reduced calorie. The group measured the amount of calories for each item of food and then found the percent difference between the measured and labeled amount of calories. The group also looked at food that was nationally advertised, regionally distributed, or locally prepared. Do the data indicate that at least one of the mean percent differences between the three groups is different from the others? The data is summarized in the table below. National Mean Standard Deviation Sample Size Local -2.1 Regional 27.1667 143.125 Fill in the hypotheses below: Ho: Select an answer Ha: Select an answer 10.3257 20.797 53.5922 20 12 8
One study found a negative correlation between participant’s age and hours of sleep they got (as they got older, they slept less). Which additional fact would lead you to believe that the relationship between age and hours of sleep is one of causation and not correlation? Jim is 63 and sleeps more than he did when he 47. Josie is 40 and sleeps fewer hours than when she was 30. The participants were randomly selected, the sample size was large, and the participants did not know the goal of the study. Jennie sometimes has difficulty sleeping.
A researcher has found a strong relationship between level of education and income and concludes that “higher levels of education cause higher income.” What error has been made?
the next 3 questions concern the results of a survey of 18,000 adults between 20 and 64 years of age. Respondents were asked to indicate whether they would endorse a public health initiative. After data were collected, the distribution of the probability of endorsing the initiative was assessed.The distribution was judged to be roughly positively skewed Four potential plots of these data are presented below (only one is correct):9. If the survey included all adults aged 18+, one more category would be inserted at the low end of the age range. What would it be? d. 18-20c. 18-19b. 15-20a. 15-19
If all of the students in a class earn the same score on a quiz, what should be said about the variability of the scores?
The study sorted PIR data into three categories: Use the graphs to estimate the following information from the study. You may wish to record your responses for use in later questions. Part A: The total number of obese men is about million. Part B: The total number of obese women is about million. Part C: The number of obese men with PIR<130% is about million. Part D: The number of obese women with PIR<130% is about million.
Questions 1, 2 and 3. In a survey of daily internet game time usage by college school students, a sample of 7 students provided the following data: 3 1.5 2.2 1.5 0.5 2.5 1 Find the mean of the data.
what would happen to the mean, median, and mode values that you calculated ,if you added one player to the team whose points per game for the season was 25. just tell me if the mean, median, and mode would go up, down, or stay the same. Give an example of variable for which the mean would not be appropriate to describe the data (that is, tell me a circumstance in which you would not want to use the mean to describe a dataset)
Question D. Give a 95% interval estimate of the number of fatal accidents per 1000 licenses in a city where 15% of the licensed drivers are under 21. Same data set as above.
