Andrews [41]

Answer:

.79 mm^2

Step-by-step explanation:

First find the area of the circle

A = pi r^2

A = 3.14 (1) ^2

A = 3.14

Now we have 1/4 of the circle

The area is 1/4 of the full area

1/4 *3.14

.785

Rounding to the nearest hundredth

.79 mm^2

An automobile manufacturer claims that its car has a 35.935.9 miles/gallon (MPG) rating. An independent testing firm has been co
Serjik [45]
<h2>Answer with explanation:</h2>

Let \mu be the population mean.

For the given claim , we have

Null hypothesis : H_0: \mu=35.9

Alternative hypothesis :  H_a: \mu\neq35.9

Since alternative hypothesis is two-tailed , so the test is a two-tailed test.

Given : Sample size : n=220  ;

Sample mean: \overline{x}=35.6  ;

Standard deviation: s=2.2

Test statistic for population mean:

z=\dfrac{\overline{x}-\mu}{\dfrac{s}{\sqrt{n}}}

z=\dfrac{35.6-35.9}{\dfrac{2.2}{\sqrt{220}}}\approx-2.02

By using the standard normal distribution table of z , we have

P-value ( two tailed test ) : 2P(Z>|z|)=2(1-P(Z

=2(1-P(z

Since , the P-value is greater than the significance level of \alpha=0.02 , it means we do not have sufficient evidence to reject the null hypothesis.
