Answer:
Step-by-step explanation:
Given that private colleges and universities rely on money contributed by individuals and corporations for their operating expenses
A recent survey of 8 private colleges in the United States revealed the following endowments (in millions of dollars)
Mean = 180.975 and std dev s = 143.042
Assuming a normal distribution we have 95% critical value is 1.96 and 99% critical value is 2.58
a) 95% Conf interval = Mean ±1.96* std error
=
Since sample size is very small confidence interval is wider.
b) 99% Conf interval = Mean ±2.58* std error
=
Since sample size is very small confidence interval is wider.
Answer:
Total minutes = 47 Minutes
Step-by-step explanation:
A telephone company in germany charges 0.12 euro per minute to call the US after a connection fee of 1.50 euro
Expressing the statement in mathematical terms;
Cost = 0.12x + 1.5 where x represens minutes
if the cost of the call was 7.14 euro, total minutes = ?
7.14 = 0.12x + 1.5
7.14 - 1.5 = 0.12x
5.64 = 0.12x
x = 5.64 / 0.12 = 47
Total minutes = 47 Minutes
