helpp on 3 and 4 you have to divide on the 3 one and it will give you a whole number. (will mark brainiest)

3 - 7

4 - 8

Step-by-step explanation:

The answer to 3 is 7 since 8.75 / 1.25 = 7

Hope I helped you and have a great day!

Please mark me as brainliest and mark me 5.0 with a thank you!

b. x- 48 =120

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;
