B. Use your calculator to find the regression line y = mx + b for men where x is the number of years since 2000 and y is the number of men. Complete the regression equation below. M(x) = c. Repeat the above steps with the data for women.

452,489 to the nearest thousand is 452,000

b. x + 1

step-by-step explanation:

i'am smart

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;
