Efficiency experts study the processes used to manufacture items in order to make them as efficient as possible. one of the steps used to manufacture a metal clamp involves the drilling of three holes. in a sample of 81 clamps, the mean time to complete this step was 56.8 seconds. assume that the population standard deviation is 9 seconds. what is the lower bound of the 98% confidence interval?

answer: no

step-by-step explanation:

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches

i believe it’s 165 because if u add 137 and 58 u get 195 and then subtract that from 360 and there’s ur answer
