In a recent survey, 336 out of 500 people chose reallygood cola as their favorite soft drink. if a similar survey was conducted out of 2,000 people, how many people would choose reallygood cola as their favorite soft drink? explain.

-3.396 = -3.4

-0.708 = -0.7

0.304 = 0.3

0.955 = 1

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;
