Given an arithmetic sequence in the table below, create the explicit formula and list any restrictions to the domain. (2 points) n an 1 40 2 47 3 54 an = 40 + 7(n − 1) where n ≥ 40 an = 40 + 7(n − 1) where n ≥ 1 an = 40 − 7(n − 1) where n ≥ 40 an = 40 − 7(n − 1) where n ≥ 1

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;

answer: b
