The perimeter of a rectangle is at most 80 inches. the length of the rectangle is 25 inches. the inequality 80 - 2w > 50 can be used to find w, the width of the rectangle in inches. solve the inequality and interpret the solution. how will the solution change in the width must be at least 10 inches and a whole number?

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;
