A department store manager has monitored the number of complaints received per week about poor service. The probabilities for numbers of complaints in a week, established by this review, are shown in the table.
| Number of complaints | 0 | 1 | 2 | 3 | 4 | 5 |
|---|---|---|---|---|---|---|
| Probability | 0.10 | 0.29 | 0.33 | 0.13 | 0.07 | 0.08 |
What is the probability of between 2 and 3 (inclusive) complaints received per week?
Please specify your answer in decimal terms and round your answer to the nearest hundredth (e.g., enter 12 percent as 0.12).
Note that the correct answer will be evaluated based on the full-precision result you would obtain using Excel.

The manager of a department store is thinking about establishing
a new billing system for the store's credit customers. She
determines that the new system will be cost effective only if the
mean monthly account is more than $170. A random sample of 400
monthly accounts is drawn for which the sample mean is $178. The
manager knows that the accounts are approximately normally
distributed with a standard deviation of $65.
Can the manager conclude from this that the new...
