Answer:
GIven,
Ho : u = 300
Ha : u != 300
test statistic t = (x - u)/(s/sqrt(n))
substitute values
= (294 - 300)/(30/sqrt(16))
= - 0.8
degree of freedom = n - 1 = 16 - 1 = 15
alpha = 0.05
P value = 0.436198
= 0.4362
Here we observe that p value > alpha, so we failto reject Ho.
So there is no sufficient evidence to support the claim.
