Josh buys a new pair of shoes at Kohl's. The tax rate is an exorbitant 11%. He put the total bill of $66.59 on his Visa card (the value of which he will pay in full when it's due to avoid the extra finance charge!) What is the cost of the shoes before tax?

c) yes, because of asa or aas

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;

the answer is $42.96
