A certain motorcycle manufacturer has been building motorcycles for 98 years. Over that period, production has increased steadily at an annual rate of 4%, so that the production rate, in motorcycles/year, after t years was r(t)=A⋅1.04^t
where A is a constant representing the initial production rate. What fraction of their total production was built during the last 10 years? Your answer should be a number between 0 and 1.

step-by-step explanation:

c

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;
