2. For a particular model of a car, a dealer offers 3 sizes of engines, 2 types of stereos, 18 body
Gnesinka [82]

The given details follow the product rule. The different model of the car available are 756.

Given that:

Engines = 3

Stereos = 2

Body=18

Color = 7

The different possibility is calculated using the following product rule:

Total =Engines \times Stereos \times Body \times Color

So, we have:

Total = 3\times 2\times 18 \times 7

Total = 756

Hence, there are 756 different models available.

Manufacturers are testing a die to make sure that it is fair (has a uniform distribution). They roll the die 66 times and record
steposvetlana [31]

Answer:

We should reject H0

At the 5% significance level, there is sufficient evidence to conclude that the die is not fair.

Step-by-step explanation:

Null hypothesis is a statement that is to be tested against the alternative hypothesis and then decision is taken whether to accept or reject the null hypothesis. The critical value is 15.091 and  test statistic is 11.070. The null hypothesis is rejected or accepted on the basis of level of significance. When the p-value Test statistics is greater than level of significance we fail to reject the null hypothesis and null hypothesis is then accepted. In the given case p-value is less than critical value then we should reject the null hypothesis.
