Question

A random sample of 500 shoppers at South Mall found that 145 favored longer shopping hours, it is claimed that fewer than 33% of the shoppers at south Mall favor longer hours give the test value that would be used for a hypothesis test. - 1.90 - 1 65 - 1.97 - 1.96 At a. 05 level of significance, the Department claims that there is no different between the variation of federal highway money distributed to the status and the variation of federal money distributed to the central states. The standard deviation for 11 northeaster states is 0.81 and the standard deviation for 12 central states is 0.35. What is test value? 2.31 1.87 5.36 3.68 The Department of Transportation claims that there is no difference between the variation of federal highway money distributed to the northeastern states and the valuation of money distributed to the central states. The standard deviation for 11 northeastern states is 0.81 and the standard deviation for 12 central states is 0.35. Using a 5% level, what is the critical value? 3.43 3.53 2.85 2.79

Explanation / Answer

as we know that test stat for equality of variance F =(s1/s2)2 =(0.81/0.35)2 =5.36

hence option C is correct
