Calculation:
The sum of all the entries divided by the total number of entries is known mean.
The formula for mean is,
\(\overline{x}=\frac{\sum x}{n}\)
Substitute the values and nas 9 in the formula,
\(\overline{x}=\frac{150+150+160+180+150+140+120+130+120}{9}\)
\(=\frac{1300}{9} = 144.444\)
Thus, the mean cost of compact refrigerators is \(\$144.44\),
0

The accompanying two-way table was constructed using data in the article “Television Viewing and Physical Fitness in Adults” (Research Quarterly for Exercise and Sport, 1990: 315–320). The author hoped to determine whether time spent watching television is associated with cardiovascular fitness. Subjects were asked about their television-viewing habits and were classified as physically fit if they scored in the excellent or very good category on a step test. We include MINITAB output from a chi-squared analysis. The four TV groups corresponded to different amounts of time per day spent watching TV (0, 1–2, 3–4, or 5 or more hours). The 168 individuals represented in the first column were those judged physically fit. Expected counts appear below observed counts, and MINITAB displays the contribution to \(\displaystyle{x}^{{{2}}}\) from each cell.

Money reports that the average annual cost of the first year of owning and caring for a large dog in 2017 is $1,448. The Irish Red and White Setter Association of America has requested a study to estimate the annual first-year cost for owners of this breed. A sample of 50 will be used. Based on past studies, the population standard deviation is assumed known with \(\displaystyle\sigma=\${230}.\)
