Asanitation supervisor is interested in testing to see if the mean amount of garbage per bin is different from 50. in a random sample of 36 bins, the sample mean amount was 49.01 pounds and the sample standard deviation was 3.7 pounds. conduct the appropriate hypothesis test using a 0.05 level of significance. a) what are the appropriate null and alternative hypotheses? h0: x = 50 versus ha: x ≠ 50 h0: μ = 50 versus ha: μ ≠ 50 h0: μ = 50 versus ha: μ > 50 h0: μ = 50 versus ha: μ < 50 correct: your answer is correct. b) what is the test statistic? give your answer to four decimal places. -1.6054 correct: your answer is correct. c) what is the p-value for the test? give your answer to four decimal places. d) what is the appropriate conclusion? fail to reject the claim that the mean amount per bin is 50 pounds because the p-value is larger than 0.05. fail to reject the claim that the mean amount per bin is 50 pounds because the p-value is smaller than 0.05. reject the claim that the mean amount per bin is 50 pounds because the p-value is smaller than 0.05. reject the claim that the mean amount per bin is 50 pounds because the p-value is larger than 0.05.

step-by-step explanation:

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
