Got a question on my math quiz asking the question below. It marked me as wrong but it didn’t tell me what I got right/wrong. Could anyone explain what I got right/wrong? Thank you so much!

0 and -99 are also a part of the set of whole numbers.

Step-by-step explanation:

Whole numbers don't have a portion that is a fraction or decimal.

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;

a: inscribed angles
