Transcribed Image Text:An auto maker is interested in information about how long transmissions last. A sample of transmissions are run
constantly and the number of miles before the transmission fails is recorded. The auto maker claims that the
transmissions can run constantly for over 150,000 miles before failure. The results of the sample are given below.
Miles (1000s of miles)
150.7
Mean
Variance
4.661
Observations
46
Hypothesized Mean
150
df
45
t Stat
2.185
p= Ex: 1.234
0.017
P(T<=t) one-tail
t Critical one-tail
P(T<nt) two-tail
t Critical two-tail
1.679
0.034
