Suppose you know that the distribution of sample proportions of nonresidents in samples of 200 students is normal with a mean of 0.46

.
Suppose you select a random sample of 200 students and find that the proportion of nonresident students in the sample is 0.43
.
a. How many standard deviations is the sample proportion from the mean of the distribution of sample​ proportions?
– 0.6
what is the answer and what is the formula?

​(Round to the nearest tenth as​ needed.)
b. What is the probability that a second sample selected would have a proportion less than 0.43
​?

​(Round to four decimal places as​ needed.)
