Calculating the margin of error

Reference no: EM1316944

Q1) Random sample of 49 pepper seeds was planted. Length of time between planting and gemination was measured. The mean time until germination was 10.4 days with a standard deviation of 2.13 days. When constructing a 95% confidence interval for the true length of time for all pepper seeds to germinate you must calculate the margin of error. The margin of error in this case is 0.60.

i) True

ii) False

With the information above calculate the critical value.

Q2) Using information from # 1 and # 2, create confidence interval of 95% for true length of time for all pepper seeds to germinate.

a) 21.27 < = mean < = 24.93

b) 9.70 < = mean < = 11.00

c) 3.13 < = mean < = 3.23

d) None of the above.
