John and Aaron are looking at a series of quiz scores. The quiz is a short quiz on which students could only score 0, 0.5, 1, 1.5, 2, 2.5, or 3 points. John claims that the quiz score is a discrete variable, and Aaron claims that it is a continuous variable. Who is correct, and why

none cuz there are no "following statements" regarding the question

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;
