5 0

Answer:

10 %

Step-by-step explanation:

15 mn = 1/4 h

We have :

\frac{\frac{1}{4} }{\frac{5}{2} } =\frac{1}{4} \times \frac{2}{5} =\frac{2}{20} =\frac{1}{10}=0.1

Then the percentage that 15 mn represents of 5/2 h is :

0.1 × 100 = 10 %

6. The mean number of hours of flying time for pilots at Continental Airlines is 37 hours per month (The Wall Street Journal, Fe
SashulF [63]

Answer:

The marginal error is 2.355

Confidence interval is (34.645,\ 39.355)

The LB and UB are 34.645 and 39.3555 respectively.

Step-by-step explanation:

Consider the provided information.

n = 49, s = 8.2 c = 95%and \bar x=37

Degree of freedom is: n-1 = 49-1 = 48.

\alpha =\frac{1-c}{2}= \frac{1-0.95}{2}\\\alpha = \frac{0.05}{2}= 0.025

From the table t_{\alpha /2}=2.010635

Marginal error is:

E=t_{\alpha /2}\times \frac{s}{\sqrt{n}}

E=2.0106\times \frac{8.2}{\sqrt{49}}

E=2.0106\times \frac{8.2}{7}

E=2.0106\times 1.171

E=2.355

Hence, the marginal error is 2.355.

Part (B)

95% confidence interval estimate

(\bar x-E,\ \bar x+E)

(37-2.355,\ 37+2.355)

(34.645,\ 39.355)

Thus, the LB and UB are 34.645 and 39.3555 respectively.
