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

Joe has 5 more than twice as many calculators as John. Write an algebraic expression. *
yarga [219]

Answer:

B. 5 + 2p

Step-by-step explanation:

<u>Let's simplify the problem:</u>

Joe has 5 + more than 2(P) as many calculators as John.

*We'll be using Addition and Multiplication operations.

If Joe has 5 more than 2 times the amount of calculators, the algebraic expression will be:

5 + 2p

p represents John's amount of calculators.

5 + (5 more than) 2(P) Twice the amount of calculators John has.
