Anew roller coaster can be modeled as a sinusoidal function. after riders are buckled into the ride at ground level, their car slowly accelerates to achieve a maximum height of 80 feet above the ground before a steep ride back to ground level. once the loop is complete the riders get 3 more turns around the track for a total of four revolutions in a one minute frame. is this function best represented by sine or cosine?

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;

what is
