The range of a data set is 18.if the smallest number is 9 , what is the largest number

27 = largest number

Step-by-step explanation:

Range = largest number - smallest number

We know the range and the smallest number

18 = largest number - 9

Add 9 to each side

18+9 =largest number-9+9

27 = largest number

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;
