What the scale factor of 3.7

Here we will explain what a Scale Factor of 3.7 means and provide you with a Scale Factor of 3.7 Calculator so you calculate either the beginning number (n) or the end number (n prime).

First things first. If you have a "number n" (n), a "number n prime" (n′) and a Scale Factor of 3.7, then it means the following:

n × scale factor = n prime

n × 3.7 = n′

In other words per the equation above, a Scale Factor of 3.7 is the factor that you would multiply with n to get n′.

Scale factor of 3.7 is 13.69

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;
