I need help rn ASAP please no links please In 1950, the population of the United States
was 152 million people. In 1990, it was 250
Million. Use a linear model to estimate the
population of the United States in 2030,
A) 326 million
B) 337 million
c) 348 million
D) 359 million
E) 360 million

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;
