How do I calculate Mean.

Add up all of the values and divide the sum by the amount of values.

For example, find the mean of 4, 6, and 14.

Add the values. 4 + 6 + 14 = 24

There are 3 terms (4, 6, and 14) so we divide their sum (24) by 3. 24 divided by 3 is 8.

The mean would be 8.

you calculatee the mean by adding all the numbers together and dividing it by how many numbers you had.

Step-by-step explanation:

example: 2, 7, 4, 2

if you add them you get 15. then you divide it by four becuas that is how many numbers you have. when you divide you get 3.75

d) 48

step-by-step explanation:

16,32,48,64,80,96,112,128,144,160,176,192,208,224,240,256,272,288,304,320,336

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;
