Answer:

The pooled estimate is given by the following formula:

$\hat p= \frac{x_1 +x_2 }{n_1 + n_2}$

And replacing we got:

$\hat p= \frac{42+45}{100+100}= \frac{87}{200}= 0.435$

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:

$\hat p= \frac{x_1 +x_2 }{n_1 + n_2}$

And replacing we got:

$\hat p= \frac{42+45}{100+100}= \frac{87}{200}= 0.435$

The other case red decreases ( means it is drawn) n blue remains so u will see the fraction above
