3. Suppose the 3 friends want to investigate the types of cars that students at WSU drive. Using the hypothetical data provided below, test whether the mean number of each type (compact mean, midsize mean, full-size mean) of cars are equal. Use \( \alpha = 0.05 \).\[\begin{array}{lccc} & \text{Compact Cars} & \text{Midsize Cars} & \text{Full-size Car} \\\hline\text{Friend/observation 1} & 650 & 453 & 469 \\\text{Friend/observation 2} & 677 & 423 & 455 \\\text{Friend/observation 3} & 703 & 515 & 401 \\\end{array}\](a) State the null and alternative hypotheses.(b) Calculate the appropriate test statistic.(c) Construct the full ANOVA table.

I need help with something regarding this problem. The National Sleep Foundation recommends that adults aged 18 to 64 get an average of 8 hours of sleep per night. A survey of sleep hours was taken during a Statistics class. The data is listed below: 4, 5, 5, 5, 5.5, 6, 6, 6, 6, 7, 7, 7, 7, 7, 7, 7, 8, 8, 8, 8, 9, 9, 9, 10, 10 Do we have enough evidence at the 0.05 significance level to say that statistics students tend to get less sleep than the recommended average of 8 hours per night? How would I get the degrees of freedom?

A data set contains the observations 3, 8, 4, 5, 3, 4, 6. A. Find the sample mean. B. Find the sample variance.
Over the first five years of owning her car, Gina drove about 12,700 miles the first year, 15,478 miles the second year, 12,675 the third year, 11,850 the fourth year, and 13,075 the fifth year. a. Find the mean, median, and mode of this data. b. Explain which measure of central tendency will best predict how many miles Gina will drive in the sixth year. a. mean= 12,700; median= 13,156; no mode; the mean is the best choice because it is representative of the entire data set. b. mean= 13,156; median= 12,700; mode= 3,628; the median is the best choice because it is not skewed by the high outlier. c. mean= 13,156; median= 12,700; no mode; the mean is the best choice because it is representative of the entire data set. d. mean= 13,156; median= 12,700; no mode; the median is the best choice because it is not skewed by the high outlier.
