Question 11 Suppose X ~ N(–3, 1). Between what x-values does 95.45% of the data lie? The range of x-values is centered at the mean of the distribution. Select the correct answer below:
between –4.69 and -1.31
between –5 and –1
between –2 and 2
between –5 and 3
Homework Answers
According to empirical rule,
Approximately, 95% ( or 95.45%) of the data lies in 2 standard deviation of the mean.
That is
95.45% data lies between mean - 2 * sd and mean + 2 * sd
between -3 - 2 * 1 and -3 + 2 * 1
between -5 and -1

4- Variance and Standard deviation (how far the data values lie from the mean) The mean, mode, and median do a nice job in telling where the center of the data set is, but often we are interested in more. For example, a pharmaceutical engineer develops a new drug that regulates iron in the blood. Suppose she finds out that the average sugar content after taking the medication is the optimal level. This does not mean that the drug is...
