PLEASE HELP The difference of the sample means of two populations is 34.6, and the standard deviation of the difference of the sample means 11.9.

The 95% confidence interval lies between and .

First BLANK:

A. -11.9
B. -23.8
C. -35.7
D. -45.4

Second BLANK:

A. +11.9
B. +23.8
C. +35.7
D. +45.4

24

step-by-step explanation:

i assuming that 2 sides are 6 the other 2 sides are 4 cm so 6 times 4 is 24 : )

answer: do you still need this?

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:

a=9
