Question

(1 point) Let x be a continuous random variable that has a distribution skewed to the right with $\mu$ = 110, and $\sigma$ = 10. Assuming n/N ? 0.05, find the probability that the sample mean, $\bar{x}$, for a random sample of 43 taken from this population will be a. less than 111.91. b. between 110.91 and 112.81. Note 1: Round your z values to 2 decimal places before looking them up in the table or using them in a calculator
