Answer:
11.False_ µ=200
12.True
13.True
14.True
15.False_ “..Critical values can be found at right and left side boundaries of non-rejection region”
16.False_ “..t-tailed and two-tailed”
17.False_”the computed t-value is -2.28” (Check the solution below)
18.False_ (Check the solution below)
19.True_(Since the t-value is less than the critical value)
20.False_ “…is not 200 grams”
Step-by-step explanation:
Solution for Part b No. 18:
For t-critical values
Significance level = 0.05
Degrees of Freedom = n - 1 = 25 - 1
Degrees of Freedom = 24 (two-tailed)
(Then look at the t-table)
T-critical values = 2.064
