Iwill give brainliestthe equation y = 15.7x + 459 can be used to predict the cost of renting a studio apartment in a certain housing complex, where x is the number of years since 2005. what if the best prediction for the cost of renting a studio apartment in this complex in 2005? a)$314.00 b)$392.50 c)$773.00 d)$851.50

the correct answer would be D 851.50

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;
