After seeing countless commercials claiming one can get cheaper car insurance from an online company, a local insurance agent wa

kifflom [539]

Answer:

Null Hypothesis, $H_0$ : $\mu_d$ = 0

Alternate Hypothesis, $\mu_d\neq$ 0

Step-by-step explanation:

We are given that a local insurance agent randomly selected profiles for 10 of his clients and checked online price quotes for their policies.

Then, based on paired data on the 10 clients (the price he offered them and the corresponding online quote), he obtained t-statistic = 0.709 p-value = 0.248.

Here , we will use the concept of Paired data test statistics because the prices that the local insurance agent offered and the corresponding online quotes are from the same single data. These information has not been taken from the two independent samples.

So, <u>Null Hypothesis</u>, $H_0$ : $\mu_d$ = 0

<u>Alternate Hypothesis</u>, $\mu_d\neq$ 0

Here, null hypothesis states that there is no difference between the price he offered them and the corresponding online quote.

On the other hand, alternate hypothesis states that there is difference between the price he offered them and the corresponding online quote.

Hence, this would be the correct null and alternative hypothesis.

When this kettle is full of water it has a mass of 2900 grams. When the kettle is half full of water it has a mass of 2050 grams

Sati [7]

If you would like to know the mass of the kettle when it is empty, you can calculate this using the following steps:

2900 grams - 2050 grams = 850 grams (half of water)

2050 grams - 850 grams = 1200 grams (no water)

The correct result would be 1200 grams.

What is the quotient of 640 and 5

MatroZZZ [7]

Answer:

128

Step-by-step explanation:

Quotient means to divide. So i.e you want to work out 640÷5.

A quick trick to divide by 5 (Without a calculator) is to double the number, and the divide by 10.

so i.e we get 640x2 = 1280.

Then 1280÷10 = 128.
