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

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
