Which of the following employees has the greatest total employee compensation? a. employee a: total job benefits $49,200 and total job expenses $300 b. employee b: total job benefits $49,500 and total job expenses $500 c. employee c: total job benefits $ 49,800 and total job expenses $700 d. employee d: total job benefits $50,100 and total job expenses $900

The correct answer is D, not C

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
