One attorney claims that more than 25% of all the lawyers in boston advertise for their business. a sample of 200 lawyers in boston showed that 63 of the lawyers had used some form of advertising for their business. at =0.05, is there enough evidence to support the attorney’s claim? (use the p-value method to test this hypothesis)

There is  enough evidence to support the attorney’s claim

Step-by-step explanation:

Given that one  attorney claims that more than 25% of all the lawyers in Boston advertise for their business.

Sample size n =200

Sample proportion =

Hypotheses:

(right tailed testat 5% significance level)

Assuming H0 to be true, std error of p =

Test statistic z = p diff/std error

=

p value for one tailed =0.0170

Since p <0.05 we reject null hypothesis

There is  enough evidence to support the attorney’s claim

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

~

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
