Rita has a collection of 96 coins consisting of nickels, dimes, and quarters. the number of dimes is 2 more than one third the number of nickels, and the number of quarters is twice the number of dimes. her friend robin has a collection of her own 98 coins, with 10 more dimes than nickels and twice as many quarters as dimes. how many coins of each kind rita has in her collection and how many coins of each kind robin has in her collection?

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;
