Answer to Problem 5E

The appropriate null and alternate hypothesis for the particular competition of ski jumpers is:

  H0:σ=3,Ha:σ>3 respectively.

Explanation of Solution

Given:

  σ=3°F

For the population value, alternate hypothesis is used the following symbols:

Proportion: p

Mean: μ

Standard Deviation: σ

Parameter: Standard Deviation of the temperature in the staner’s cabin.

The valued mentioned to claim is equal to the population value is given by the null hypothesis:

  H0:σ=3

And the alternate hypothesis is exactly opposite to null hypothesis:

  Ha:σ>3

Conclusion:

So the hypothesis test is:

  H0:σ=3Ha:σ>3
