Given that:
x_bar=150, σ=36, n=60
The 90% confidence interval will be found as follows:
+/-1.65(36/sqrt(60))
=+/-1.65(4.64758)
=+/-7.6685
Thus our answer will be:
150+/-7.6685
=157.6685 or 142.3315

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

(02.05 mc) determine if the two figures are congruent and explain your answer.
