A mechanic began pouring a full can of motor oil into a funnel. The can of motor oil has a radius of 2.5 inches and a height of 6 inches. The funnel has a radius of 3 inches and a height of 5.5 inches. If the hole on the bottom of the funnelo
is plugged so that the funnel is not able to drain, what percentage of the oil would remain in the can after the funnel is
completely filled?
A. 21%
B. 44%
C. 56%
D. 79%

the answer is d on edge

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;
