Answer:

-4

Step-by-step explanation:

Low tide is 1 ft below average water level.

High tide is 5 ft higher than low tide.

High tide is 5 ft higher than low tide. Start at low tide. Use 1 ft of the 5 ft to go up to average water level. You still have 4 ft more to go to high tide. That means high tide is 4 ft above average water level. Then, the average water level is 4 ft below high tide. A height below another height is is a negative number of feet from that height. Since the average water height is 4 ft BELOW high tide, then relative to high tide, the average water level is -4 ft.

Answer: -4

A local environmental group was interested in estimating the total amount (in pounds) of recycled material that is collected wee
lina2011 [118]

Answer:

95% confidence interval for the mean amount of recycled material from all households in Clemson is between a lower limit of 3.875 pounds and an upper limit of 4.125 pounds.

Step-by-step explanation:

Confidence interval is given as mean +/- margin of error (E)

mean = 4 pounds

sample sd = 0.5 pound

n = 64

degree of freedom = n-1 = 64-1 = 63

confidence level (C) = 95% = 0.95

significance level = 1 - C = 1 - 0.95 = 0.05 = 5%

Critical value (t) corresponding to 63 degrees of freedom and 5% confidence level is 1.9982

E = t×sample sd/√n = 1.9982×0.5/√64 = 0.125 pound

Lower limit of mean = mean - E = 4 - 0.125 = 3.875 pounds

Upper limit of mean = mean + E = 4 + 0.125 = 4.125 pounds

95% confidence interval is (3.875, 4.125)
