Earlier this month, 69% Californians voted 'yes' on Measure H: a sales tax measure to fund homeless services and prevention. Sample of size 50 is taken randomly from the population. Find the 20th percentile for the above distribution of sample proportions. i. e Find P(^p < or =?) = 0.20.A. 0.74.B. 0.64.C. 0.59.

55? i think maybe

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;
