Francisco Goya computed the unit price of an 8-count package of hamburger buns and found them to be $0.03 more per bun than the unit price of a 10-count package. If the 8-count package costs $0.45 less than the cost of the 10-count package, find the cost of the 8-count package and the 10-count package.

it’s supposed to be -4+45=41

step-by-step explanation:

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;
