Suppose a random sample of 51 fatal crashes in 2015 in whichdriver had a positive blood alcohol concentration (BAC) results ina mean BAC of 0.158 gram per deciliter (g/dL) with a standarddeviation 0.010 g/dL. Construct and interpret the 99% confidenceinterval for the mean BAC in fatal crashes in which the driver hada positive BAC. Use 4 non-zero decimal places in yourcalculations.
a. Find the t-alpha/2,df
b. Find and the margin of error (ME).
c. Find the Upper bound and the Lower bound. Interpret theconfidence interval.
