pishuonlain [190]

Answer:

(a) Continuous,

(b) Discrete,

(c) Continuous.

Step-by-step explanation:

We are asked to classify each variable as discrete or continuous.

(a) The time it takes to drive to University.

We know that continuous data can take any values within a range, while discrete data can take only certain values.

Height, weight, time are typical examples of continuous data.

Since it can take some minutes or hours to reach university, therefore, the given variable is continuous.

(b) The number of credit cards a person has.

The number of credit cards a person can take lie in the group of positive integers. Since a person can take finite number of credit cards, therefore, the given variable is discrete.

(c) The weight of pumpkins.

We know that the weight of all pumpkins cannot be similar. The weight of pumpkins can be between some kg to some pounds, therefore, the given variable is continuous.

This is easy. He first earned $11 on Saturday and then on Sunday he earned some money. We don't know how much he earned, we just know he earned some money. Let's put the expression together. A good place to start would be the $11. Let's add eleven to the expression. And because he earned some more money, it's going to be addition. So currently, the expression stands at $11 +
And because we don't know how much money he made on Sunday, x will be the variable for how much he earned. So the expression will be

11 + x

Census Bureau data shows that the mean household income in the area served by a shopping mall is $64,500 per year with the stand

Elenna [48]

Considering the situation described, the null hypothesis is given as follows:

$H_0: \mu = 64,000$ .

<h3>What are the hypothesis tested?</h3>

At the null hypothesis, it is tested if the <u>mean is the same as in the Census</u>, of $64,000, hence:

$H_0: \mu = 64,000$ .

At the alternative hypothesis, it is tested if the mean is different from the Census, hence:

$H_1: \mu \neq 64,000$ .
