Salaries of 50 college graduates who took a statistics course in college have a mean, X. of $67,100. Assuming a standard deviation, c. of $18,022, construct a 95% confidence interval for estimating the population mean

correct answer:

b.(19,-2)

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
