Answer:
The p-value is 0.0229
Step-by-step explanation:
With
we have an upper-tail alternative. Because the p-value is defined as the probability of getting a value at least as extreme as the value observed. The observed value is given by the test statistic z = 1.997 which comes from a standard normal distribution. Therefore, we compute the p-value in the following way P(Z > 1.997) = 0.0229, i.e., the p-value is 0.0229
Answer:
perimeter=2(L+W)
304=2(81+W)
Step-by-step explanation:
304=162+2W.2W=304-162.2W=142\2=71
