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)

Step-by-step explanation:
A few are 0.250 0.2500 0.25000
The are all equivalent because just adding zeroes on the end doesn't change the value of the decimal.
