Step-by-step explanation:
the explanation on D
A^2 + b^2 = c^2
(500)^2 + (1200)^2 = c^2
1,690,000 = c^2
take the square root of 1,690,000

Answer:
a) The level of significance is large because here z is not appropriate.
b) The true critical value is larger than z because the level of significance is large.
Step-by-step explanation:
a) Based on the question under consideration, the true level of significance is larger than .05 level of significance is large, the reason being that z is not appropriate in this case.
b) The true critical value is larger than that of the critical z, this is because the level of significance is large.
t* in P(T > t*) = 0.975 is more than z* = 1.96 in P(z> z*) =0.975
