The median is 12 attempts and the mean is 11.5 attempts. After reviewing the data, it is determined that 2 should not be included since that was an exhibition game rather than a regular game during the season. A. What happens to the median if 2 attempts is removed from the data set?

B. What happens to the mean if 2 attempts is removed from the data set?

so then what are you asking?

step-by-step explanation:

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: your correct answer is b. d.
