H_a: μ > 50, n = 55,

= 51, σ = 3.6
◦ z = 2.06; not supported
◦ z = 3.29; not supported
◦ z = 6.25; supported
◦ z = 2.06; supported

Question 2

Find the value of the standard score, z, and determine whether the alternative hypothesis is supported or not supported at a 0.05 significance level.

H_a: μ < 10, n = 18 ,

= 7.5, σ = 1.7
◦ z = 7.5; supported
