In a random sample of 300 women, 49% favored stricter gun control legislation. in a random sample of 200 men, 28% favored stricter gun control legislation. construct a 98% confidence interval for the difference between the population proportions p1 - p2

Construct a 98% confidence interval for the difference between the population proportions p1 - p2 is ( 0.110199 and 0.309801)

Step-by-step explanation:

Given data

sample n1 = 300 women

sample n2 =  200 men

control legislation f1 = 49% = 0.49

control legislation f2 = 28% = 0.28

to find out

Construct a 98% confidence interval for the difference between the population proportions p1 - p2

solution

we know difference of control legislation = f1 -f2

so difference is 0.49-0.28 = 0.21

so for 98% confidence  Z value is 2.326 from standard table

and interval for difference formula is

f1 - f2 - Z

and

f1 - f2 + Z

put all these value and we get difference of population proportion are

0.49 - 0.28 - 2.326

and

0.49 - 0.28 + 2.326

= 0.110199

and

= 0.309801

Construct a 98% confidence interval for the difference between the population proportions p1 - p2 is ( 0.110199 and 0.309801)

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
