Question

We assumed that the amount of money spent in a shopping
trip follows Normal Distribution with the average of  μ 0  = 98 €. This assumption has
been tested on a sample of size  n 
 =9 . The sample mean has been

=  88.4 € with
the  sample standard deviation  of  s   = 15.5 €. 
 Taken Significance Level of  0.12 , the Rejection Region for H 0    (μ   =
μ 0 ) is (find the closest answer):

Answer

[0, μ 0  – 9.5] ⋃ [μ 0  + 9.5, ∞)

Answer

[0, μ 0  – 8.5] ⋃ [μ 0  + 8.5, ∞)

Answer

[0, μ 0  – 8] ⋃ [μ 0  + 8, ∞)

Answer

[0, μ 0  – 9] ⋃ [μ 0  + 9, ∞)

Answer

[0, μ 0  – 10] ⋃ [μ 0  + 10, ∞)
