30% of the sampled students <u>have three or more siblings</u> at home.

<u>Step-by-step explanation</u>:

<u>step 1</u> : The total number of students sampled = 20 students.

<u>step 2</u> : The students having three or more siblings = 6 students.

The question asks for what percentage of the sampled students have three or more siblings.

<u>step 3</u> : Let the unknown percentage be X%

X% of total sampled student = students having 3 or more siblings

(X/100) \times 20 = 6 students.

2x = 6\times10

x = \frac{60}{2}

x = 30 %

A past study claims that adults in America spend an average of 17 hours a week on leisure activities. A researcher wanted to tes
8090 [49]

Answer:

The claim is false.

Step-by-step explanation:

Given the data :

13 24 21 37 15 25 18 22 40 32

The sample mean and standard deviation can ben calculated for the given sample.

Using calculator :

Sample mean, xbar = 24.7

Sample standard deviation, s = 9.04

Sample size, n = 10

The hypothesis :

H0 : μ = 17

H1 : μ ≠ 17

The test statistic :

(xbar - μ) ÷ (s/√(n))

(24.7 - 17) ÷ (9.04/√(10))

7.7 / 2.8586990

Test statistic = 2.694

We can obtain the Pvalue, at α = 0.05 ; df = n-1 = 9

Pvalue = 0.0246

Since Pvalue < α ; we reject the null ; Hence, there is significant evidence to conclude that an adult American does not spend average of 17 hours in leisure
