Question

A survey was taken of the heights, in inches, of 20-to 29-year-old males. A simple random sample of n = 15 males 20 to 29 years old results in the data in the table, Construct a 95% t-interval about the population mean Decide if a 95% t-interval can be constructed about the population mean. If not, state the reason why 65.3 72.3 65.1 68.2 66.9 70.3 72.7 73.3 68.7 72.7 69.1 67.1 68.6 71.8 OA. A t-interval can be constructed OB. A t-interval can not be constructed because the data is not normal ° C. A t-interval can not be constructed because there is an outlier c 70.7 For convenience, a normal probability plot and boxplot are given Percent 75 25 60 80 65 70 75 Height Height

Explanation / Answer

From normal probability plot, we can see that any point is not outside the limits.

From boxplot, we can see that there is no outlier and the distribution is roughly symmetric.

Hence,

A t - interval can be constructed.

Option A is correct.
