Test whether the number of cakes produced has any effect on sales based on the F-test at the5% level of significance. State the hypotheses, decision rule and conclusion.(d) By considering the Q-Q plot in Figure 10, what can you conclude?(c) A cake shop produces different kinds of cakes a day. The number of cakes produced (x) isthroughout to be linearly related to the sales (y) amount of that particular day. The data werecollected on 15 successive days in Table 10.

A study is undertaken to investigate the self-reported health status among women with osteoporosis. Health status is measured on a scale from 0 to 100, with higher scores indicative of better health status. A sample of 9 subjects is reported and the box plot below is generated to describe the data. Select all of the correct answers using the box plot. 75 70 65 60 55 30 45 40 35 30 Health Status O Q1- 40 O There are no outliers. O IQR - 50 O Q3 - 70 O 35 and 80 are the outliers O Q2 (aka: Median) is approximately 48.

Statistics teacher realize that his students keep using cell phones during the class. Then he did some research and found out that people use cell phones for 7.2 hours per day on average, and usage time variability around that average is 2.0449. Then he decides to give an assignment of reading books as an alternative of cell phone usage in exchange of 50 extra credit to their statistics exam. After the exam, he collected the data of cell phone usage time from his 127 students and calculated the average cell phone usagetime drops to 6.8 hours per day. a) Under the assumption that probability of uncontrolled factors leading you the wrong statistical decision is five percent, conduct the statistical analysis to decide wheter decrease in the cell phone usage time is real or it happens just because of the random chance b)and interpret the results
(a ) Calculate the mean of the distribution . (b ) Calculate the 10% trimmed mean . ( c) Why is the trimmed mean a better summary of the center of this distribution than the mean?
