In the Present Value of an Ordinary Annuity formula, what does the n represent?
Ierofanga [76]
N represents the number of payment periods.  Supposing you arranged for a mortgage to buy a house; you'd have to make n payments of so many dollars per month to pay off the mortgage (the total amount due,with interest).  

If the annual interest rate were r, and payments were due monthly (12 payments per year), then the monthly interest rate would be r/n = r/12.  The typical 30-year mortgage involves monthly payments over a 30 year time span.  This comes to 360 monthly mortgage payments.

Previous studies have reported that elite athletes are often deficient in their nutritional intake (for example, total calories,
Naddik [55]

Answer:

(3138.29, 3705.11)

Step-by-step explanation:

Given that for sample size of n = 50 male athletes from eight Canadian sport centers  surveyed, the average caloric intake was 3077.0 kilocalories/day with a sample standard deviation of 987.0.

The recommended amount = 3421.70

To construct 95% confidence interval

Since population std deviation is not known we use t critical value for degree of freedom 50-1 =49

t critical = 2.010

Hence margin of error = 2.010*\frac{987}{\sqrt{50-1} } \\=283.41

Confidence interval lower bound = 3421.70-283.41\\=3138.29

Confidence interval upper bound = 3421.70+283.41\\=3705.11

Conf interval = (3138.29, 3705.11)
