Use the given information to find the P-value. Also, use a 0.05 significance level and state the conclusion about the null hypot

hesis (reject the null hypothesis or fail to reject the null hypothesis).

a. 0.1031; fail to reject the null hypothesis
b. 0.0516; reject the null hypothesis

Answer: a. 0.1031; fail to reject the null hypothesis

Step-by-step explanation:

Given: Significance level : \alpha=0.05

The test statistic in a two-tailed test is z = -1.63.

The P-value for two-tailed test : 2P(Z>|z|)=2P(Z>|-1.63|)=0.1031 [By p-value table]

Since, 0.1031 > 0.05

i.e. p-value > \alpha

So, we fail to reject the null hypothesis. [When p<\alpha then we reject null hypothesis  ]

So, the correct option is a. 0.1031; fail to reject the null hypothesis.

City planners are planning to build a new community pool. They agree that the pool will be rectangular in shape, but the propose
kobusy [5.1K]

The equation that can be used to determine the original length of the pool is 205.85 = 11.6(l + 3.7)

Let l be the original length of the pool.

Since the length of the pool is increased by 3.7 m, the new length L = l + 3.7.

Also, the area of the pool A = 205.85 square meter and it is a rectangle with width, W = 11.6 meters,

So, A = LW

Substituting the values of the variables into the equation, we have

A = LW

205.85 = (l + 3.7)11.6

So, the equation that can be used to determine the original length of the pool is 205.85 = 11.6(l + 3.7)
