Did I calculate this correctly? Thank you.

6.2.1 We wish to estimate the average number of heartbeats per minute for a certain population
The average number of heartbeats per minute for a sample of 49 subjects was found to be
90. Assume that these 49 patients constitute a random samplc, and that the population
normally distributed with a standard deviation of 10.
