Question: The following TI-84 Plus display presents some sample statistics. a. Assume that a histogram of the sample is bell-shaped. Approximately what percentage of the sample

The following TI-84 Plus display presents some sample statistics.x=79 1-Var Stats =2291 Ex2=182361 Sx=7 ax=6.878251582 n=29 minX=69 +Q1=72

a. Assume that a histogram of the sample is bell-shaped.
Approximately what percentage of the sample values are between 72 and 86?

b. Assume that a histogram for the sample is bell-shaped.
Between what two values will approximately 95% of the sample be?

c. If we do not assume that the histogram is bell-shaped, at least what percentage of the sample values will be between 65 and 93?
