Joe spends 18.75% of his working day washing cars. He spends 1.5 hours washing cars. How many total hours does he work per day?

insens350 [35]

Answer:

8 hours

Step-by-step explanation:

Joe spends 18.75% of his working day washing cars.

Joe spends 1.5 hours washing car.

Therefore 18.75% is equal to 1.5 hour.

18.75% = 1.5 hour

1% = 1.5 ÷ 18.75 = 0.08 hour

100% = 0.08 x 100 = 8 hours

You wish to compare the prices of apartments in two neighboring towns. You take a simple random sample of 12 apartments in town

Rom4ik [11]

Answer:

The value of P-value is 0.0472.

Step-by-step explanation:

We are given that you take a simple random sample of 12 apartments in town A and calculate the average price of these apartments. You repeat this for 15 apartments in town B.

Let $\mu_1$ = true average price of apartments in town A

$\mu_2$ = true average price of apartments in town B

So, Null Hypothesis, $H_0$ : $\mu_1=\mu_2$

Alternate Hypothesis, $H_A$ : $\mu_1\neq \mu_2$

The test statistics that have been used here is two-sample t-test statistics, i.e;

The test statistics given to us is 2.1

Now, the P-value of the test statistics is given by the following formula;

P-value = P( $t__n__1+_n_2-_2$ > 2.1)

= P( $t_2_5$ > 2.1) = 0.0236

In two-tailed test, P-value is calculated as = 2 $\times$ 0.0236 = 0.0472

Hence, the value of the p-value is 0.0472.
