1. The producer of a fuel added substance guarantees that the utilization of this added substance expands gas

mileage. An arbitrary example of 6 vehicles was chosen, and these vehicles were driven for one

week without the gas added substance and afterward for multi week with the added substance. The

following table gives the mileage (in miles per gallon) for these vehicles with and without the

added substance:

Vehicle 12 3 4 5 6

Mileage Without Additive 24.6 28.3 18.9 23.7 15.4 29.5

Mileage With Additive 26.3 31.7 18.2 25.3 18.3 30.9

Asuming mileages are ordinarily circulated, would you be able to infer that the utilization of the fuel

added substance expands mileage at the 2.5% importance level?

2. A scientist wished to appraise the contrast between the extent of clients of two

shampoos who are happy with the prodcut. In an example of 400 clients of Shampoo A

3. A study as of late detailed that the mean public yearly consumption for inpatient and

outpatient administrations of all people more than 64 years old was $5,423 with a norm

occupants over age 64 is higher than the public normal of $5,423? Utilize the .01

level of importance.
