11. The Gateway Arch in St. Louis, Missouri is a wonderful tourist attraction. The arch has a maximum height of 630 feet and covers a horizontal (ground) distance of 630 feet. The
arch reaches its maximum height at a horizontal distance of 315 feet.
a. Write the equation that represents this situation in the form that reveals the
mentioned key feature. Let d represent the horizontal distance the arch covers in
feet and H(d) represent the height of the arch at any given horizontal distance.
Let a =-0.01. (Hint: sketch and label the graph.)
b. Explain why you choose this particular form.

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;
