Answer:
The expression for the total amount of Jamal earned is $ (14 y + 55)
Step-by-step explanation:
Given as :
The bonus amount earn by Jamal = $ 55
According to question
On Thursday
∵ For 1 hour of work , Jamal earn y dollars
∴ For 9 hours of work , Jamal will earn 9 × y = 9 y dollars
On Friday
∵ For 1 hour of work , Jamal earn y dollars
∴ For 5 hours of work , Jamal will earn 5 × y = 5 y dollars
So, The total earning on both days of his work = 9 y + 5 y = 14 y dollars
Since Jamal also earn bonus of $ 55
So, Total earning of Jamal including bonus = 14 y + $ 55
Hence The expression for the total amount of Jamal earned is $ (14 y + 55) Answer

a. The inference made involves estimation. The question provided that the statements were made on the basis of the resulting data and not on the basis of some hypothesis testing.
This implies that some statistics were calculated from sample data to approximate the population parameter, as shown in the statements. The statements were not an attempt to establish the statistical significance of some claims.
b. The population of interest is American teenagers between 12-17.
Step-by-step explanation:
An inference from data is a statistical estimation by which some statistics are calculated based on the sample data of 800 teens between the ages of 12 and 17. The statistics serve as an approximation to the population parameter.
Inference based on hypothesis testing establishes if a claim has statistical significance by providing statistical evidence in favor of the claim or against it.
