Question

A calculus exam has a mean of µ = 73 and a standard deviation of σ = 4. Trina's score on the exam was 79, giving her a z-score of +1.50. The teacher standardized the exam distribution to a new mean of µ = 70 and standard deviation of σ = 5. What is Trina's z-score for the standardized distribution of the calculus exam?

Answer 1

Answer:

I get z = +1.8

x= 79

m= 73;s= 4;z= (x-m)/s= 1.5
