You want to buy new pair of Air Jordans but you don’t have the money for them you borrow 130 from your sister to buy the shoes t
Firlakuza [10]

You do not have enough money to pay your sister back and the amount left is $29

<h3>A. Do you have enough money to pay your sister back? </h3>

The given parameters are:

Amount borrowed = $130

Earnings = $12 per hour for 4 hours

Earnings = $12 per hour for 6 hours

Tip = $5

The total earnings is

Total = 12 * 4 + 12 * 4 + 5

Evaluate

Total = $101

101 is less than 130

Hence, you do not have enough money to pay your sister back

<h3>How much money left</h3>

The amount left is calculated as:

Amount left = $130 - $101

Evaluate

Amount left = $29

Hence, the amount left is $29

A taxi company manager is trying to decide whether the use of radial tires instead of regular belted tires improves fuel economy
siniylev [52]

Answer:

Step-by-step explanation:

Corresponding gasoline consumption when radial tires is used and gasoline consumption when regular belted tires is used form matched pairs.

The data for the test are the differences between the gasoline consumption when radial tires is used and gasoline consumption when regular belted tires is used.

μd = the gasoline consumption when radial tires is used minus the gasoline consumption when regular belted tires is used.

For the null hypothesis

H0: μd ≥ 0

For the alternative hypothesis

H1: μd < 0

The resulting p-value was .0152.

Since alpha, 0.05 > than the p value, 0.0152, then we would reject the null hypothesis. Therefore, at 5% significance level, we can conclude that the gasoline consumption when regular belted tires is used is higher than the gasoline consumption when radial tires is used.
