Calculate the appropriate test statistic.
The test statistic is
nothing.
(Round to two decimal places as needed.)
Determine the appropriate critical value(s).
The critical value(s) is(are)

Consider the hypothesis statement to the right.
State your conclusion given thatsequals=3.4,
nequals=27,
andalphaequals=0.05.
Upper H 0H0:
sigma squared2less than or equals8.0
Upper H 1H1:
sigma squared2greater than>8.0
Explanation / Answer
Method
Null hypothesis -squared = 8
Alternative hypothesis -squared > 8
The chi-square method is only for the normal distribution.
The Bonett method cannot be calculated with summarized data.
