Answer #1

Sorry as per the HOMEWORKLIB RULES I'm only allowed to solve the first question

1)

This is a normal distribution question with

Sample size (n) = 44

Since we know that

P(x < 62000.0)=?

The z-score at x = 62000.0 is,

z = -2.6747

This implies that

Option B is correct: Only 0.37% of sample of 44 specialist will have an mean salary less than 62000. This is an unusual event.

PS: you have to refer z score table to find the final probabilities.

Please hit thumbs up if the answer helped you
