Question

We assumed that the amount of money spent in a shopping

been tested on a sample of size  n 
 =8 . The sample mean has been

=  95.7 € with
the  sample standard deviation  of  s   = 13.1 €. 
 Taken Significance Level of  0.05 , the Rejection Region for H 0    (μ   =
μ 0 ) is (find the closest answer):

Answer

[0, μ 0  – 7] ⋃ [μ 0  + 7, ∞)

Answer

[0, μ 0  – 11] ⋃ [μ 0  + 11, ∞)

Answer

[0, μ 0  – 8] ⋃ [μ 0  + 8, ∞)

Answer
