QUESTION 19

Hypothesis Testing Fundamentals (Part 3 of 5)

Suppose you are determining whether the depth of groves cut into aluminum by a milling machine is deeper than 1.7 mm. You cut 14 groves, then measure the depth of each one. With these measurements, you perform a statistical hypothesis test to determine whether the groove depth is equal to 1.7 mm. Which of the following tests would you use?

This one-sided test:

H₀: = 1.7 mm

H₁: > 1.7 mm

This one-sided test:

H₀: = 1.7 mm

H₁: < 1.7 mm

This two-sided test:

H₀: = 1.7 mm

H₁: 1.7 mm

This two-sided test:

H₀: > 1.7 mm

H₁: = 1.5 mm

QUESTION 20

Hypothesis Testing Fundamentals (Part 4 of 5)

Suppose you are measuring the temperature at which rocket propellant burns to determine whether it is higher than the maximum temperature at which the rocket nozzle will not be damaged. Which of the following tests would you use?

This two-sided test:

H₀: = 2500 degrees F

H₁: 2500 degrees F

This two-sided test:

H₀: gt; 2500 degrees F

H₁: = 2500 degrees F

This one-sided test:

H₀: = 2500 degrees F

H₁: > 2500 degrees F

This one-sided test:

H₀: = 2500 degrees F

H₁: < 2500 degrees F

QUESTION 21

Hypothesis Testing Fundamentals (Part 5 of 5)

Suppose you are testing ground water samples for the presence of salt. A level of salt of more than 50 mg/L is an indication that remedial action is required. You decide to perform a statistical hypothesis test to determine from the salt concentrations in 16 ground water samples whether the salt concentration is above 50 mg/L. Which of the following tests would you use?

This two-sided test:

H₀: = 50 mg/L

H₁: 50 mg/L

This two-sided test:

H₀: > 50 mg/L

H₁: < 45 mg/L

This one-sided test:

H₀: = 50 mg/L

H₁: < 50 mg/L

This one-sided test:

H₀: = 50 mg/L

H₁: > 50 mg/L
