Assume that you plan to use a significance level of α= 0.05 to test the claim that p1 = p2. Use the given sample sizes and numbers of successes to find the pooled estimate p. Round your answer to the nearest thousandth.
n1 = 100,
n2 = 100,
x1 = 42,
x2 = 45

Answer:

The pooled estimate is given by the following formula:

[tex] \hat p= \frac{x_1 +x_2 }{n_1 + n_2}[/tex]

And replacing we got:

[tex] \hat p= \frac{42+45}{100+100}= \frac{87}{200}= 0.435[/tex]

Step-by-step explanation:

We have the following info given:

n1 = 100,

n2 = 100,

x1 = 42,

x2 = 45

The pooled estimate is given by the following formula:

[tex] \hat p= \frac{x_1 +x_2 }{n_1 + n_2}[/tex]

And replacing we got:

[tex] \hat p= \frac{42+45}{100+100}= \frac{87}{200}= 0.435[/tex]
