HERE I AM AGAIN, HELP
ILL GIVE BRAINLIEST <3

For number three I think the blank represents 1.25

Step-by-step explanation:

For the third one:

I named the answer / total as x

-x - 2.25 = x

-x + 2.5 + 2.5 = x + 2.5

Simplifying it would give 1.25

(I'm unsure for the answer but I tried!)

HOPE THIS HELPS!!

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;

cause it equals more
