Question
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...
This test statistic leads to a decision to...
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 )
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 )
