3.44 scooping ice cream. ice cream usually comes in 1.5 quart boxes (48 fluid ounces), and ice cream scoops hold about 2 ounces. however, there is some variability in the amount of ice cream in a box as well as the amount of ice cream scooped out. we represent the amount of ice cream in the box as x and the amount scooped out as y . suppose these random variables have the following means, standard deviations, and variances: mean sd variance x 48 1 1 y 2 0.25 0.0625 (as) an entire box of ice cream, plus 3 scoops from a second box is served at a party. how much ice cream do you expect to have been served at this party?

my acc plz

step-by-step explanation:

answer: you need the equation in the question so i can answer it

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;
