a. H0 : U ≥ 15

   Ha : U < 15

b. Type I error is incorrectly conclude that the pain is reduced in less than 15 minutes.

c. Type II error is fail to conclude that time for pain reduction is less than 15 mints when actually its less than 15 minutes.

Type I error is one in which we reject a true null hypothesis.

Type II error is one in which we fail to reject the null hypothesis that is actually false.

lesya [120]

Most fluorescent lamps with energy savings ballasts, compact fluorescent lamps (cfls), leds, and halogen lamps meet high-efficacy requirements, but conventional incandescent lamps do not.

An electric light with a wire filament that has been heated until it glows is called an incandescent light bulb. To prevent oxidation, the filament is encased in a glass bulb with a vacuum or inert gas. Light is produced by incandescent bulbs by heating a metallic filament. Light is produced via gas discharge, or exciting the gas, in fluorescent lamps. More electricity is used by incandescent bulbs. For the same rating, fluorescent bulbs use less electricity.

iren [92.7K]

Answer:

Gross Pay 300 dollar

Federal Income Tax $ 30

FICA $ 22.95

SUTA $ 9

Net Pay: 238.05

As a percentage of gross pay: 79.35%

Explanation:

Gross pay:

20 hours x $15 each = $ 300

Taxes:

income tax: 300 x 10% = 30

FICA 300 x 7.65% = 22.95

SUTA taxes 300 x 3% = 9

Net pay 300 - 30 - 22.95 - 9 = 238.05

Net pay as a percentage of gross pay:

238.05 / 300 = 0.7935 = 79.35%
