During her lunch hour, Shawna asked 40 students how many after-school clubs they joneu. THICH WIVE
of clubs that the students joined.
2,2,3,0, 3, 2, 4, 2, 1, 4, 3, 2, 4, 1, 0, 2, 1, 3, 2, 0,
1, 1, 2, 1,0,3,0, 1, 4, 1, 1, 0, 2, 3, 2, 0, 3, 2, 0, 1
If this sample is representative of the student population of 360 students, about how many students in the school joi
clubs?
15 students
63 students
109 students
189 students
O

maybe 15 students or 63 students and if not I am sorry of that's wrong

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;
