What is the standard deviation for a score of X = 40 from a population with a µ = 50 and a z = - 2.00?
Homework Answers
Solution:-
Given that,
mean = 
= 50
x = 40
z = -2.00
Using z-score formula,
x = z * 
+
40 = -2.00 * + 50
= 40 - 50 / -2.00
= 5

2. Hypothesis tests about a population mean, population standard deviation known Lenders tighten or loosen their standards for issuing credit as economic conditions change. One of the criteria lenders use to evaluate the creditworthiness of a potential borrower is her credit risk score, usually a FICO score. FICO scores range from 300 to 850. A consumer with a high FICO score is perceived to be a low credit risk to the lender and is more likely to be extended credit...
