From glamourous gap-year inspired dressing to dresses with fringe benefits, see the trend on the catwalk here.

1. H0: μ = 28 and H1: μ < 28
ReplyDeleteThe test statistic value is t = −1.96.
The P-value is 0.0287
So reject Chrysler’s claim: Dodge Caravans are getting 28 mpg.
2. The hypotheses are H0: σ = 2.1 and H1: σ > 2.1
The value of our test statistic is 156
The associated P-value is approximately zero.
So reject Chrysler’s claim: The standard deviation is 2.1 mpg.
3. Chrysler should lower the highway miles per gallon of the Dodge Caravans and reduce variability in miles per gallon.
4. In some cases the mean is acceptable. If there is large variables about the mean there will be complaints because of inconsistencies.
