The manager of McDonald's is concerned that the patrons are not consistently receiving the same amount of French fries with each order. The chef claims that the standard deviation for a 10-ounce order of fries is at most 1.7 oz. But the manager thinks it may be higher, so she randomly weighs 24 orders of fries, which yield a mean of 11 oz and a standard deviation of 2.1 oz. What can you conclude if α=0.1 H0:σ2 Ha:σ2 (Select an answer: not equal to  != greater than  > less than  <)   df =  χ2= P-value =  The p-value is... greater than αα less than (or equal to) αα This test statistic leads to a decision to... fail to reject the null accept the null reject the null accept the alternative As such, the final conclusion is that there (Select an answer is / is not ) sufficient evidence to conclude the standard deviation in french fry weight is (Select an answer different / less / greater)  than (11 / 2.1 / 1.7 )
