In a large sample of customer accounts, a utility company determined that the average number of days between when a bill was sent out and when the payment was made is 42 with a standard deviation of 8 days. Assume the data to be approximately bell-shaped.1. Between what two values will approximately 95% of the numbers of days be?

Approximately 95% of the numbers of days will be between 26 and 58.

Step-by-step explanation:

We are given the following in the question:

Mean, μ = 42

Standard Deviation, σ = 8

We are given that the distribution of average number of days between a bill is a bell shaped distribution that is a normal distribution.

Empirical Formula:

Thus, by Empirical formula 95% of data lies within two standard deviation.

Thus, approximately 95% of the numbers of days will be between 26 and 58.
