After a tropical storm in a certain state, news reports indicated that 19 percent of households in the state lost power during the storm. A state engineer believes that estimate is too low. The engineer will collect data to perform a hypothesis test on the proportion of all households without power. Which of the following are the appropriate hypotheses for such a test?

Answers

Answer 1

Answer:

D

Step-by-step explanation:

The null hypothesis is that p=0.19. The engineer says that this estimate is too low, meaning he believes the true proportion is greater than 0.19 - p>0.19. Because this is a proportion of ALL houses in the state, we use p rather than phat, leaving D as the correct answer.

Stacy spins the pointer 120 times and records it. The pointer lands 30 times on a section numbered 2, 19 times on 3, 25 times on 4, 29 times on 5, and 17 times on 6. A winning spin is a 2. FIND THE EXPERIMENTAL PROBABILITY OF LANDING ON 2

Answers

Answer:

1 / 4

Step-by-step explanation:

Number of trials = 120

Landing on 2 = 30

Landing on 3 = 19

Landing on 4 = 25

Landing on 5 = 29

Landing on 6 = 17

The experimental probability of landing in a two:

Experimental probability :

Number of times event occurs / Number of trials

Number of 2 landings = 30

Experimental probability of landing in a 2 ;

30 / 120 = 1/4

Step-by-step explanation:

h(t)=- 16t^2 +16t+12 zeros of the parabola

Answers

Step-by-step explanation:

h(t) = -16t² + 16t + 12

h(t) = -4(4t² - 4t - 3)

h(t) = -4(2t - 3)(2t + 1)

When h(t) = 0, we have t = 1.5 or t = -0.5.

Hence the zeroes are 1.5 and -0.5.
