If Mr. O'Brien cuts five lawns per day at $40 each, and he has a goal of making $3500, how many days will it take to reach that

Ede4ka [16]

Answer:

17 days and a half.

Step-by-step explanation:

First, we can find how much money he makes per day cutting lawns. This can be found with the equation:

40 x 5 = 200

He makes $200 a day cutting lawns.

Now we can divide his goal money ($3500) by his daily rate ($200) to get the number of days it will take to reach his goal.

3500 ÷ 200 = 17.5

It will take him 17.5 days to reach his goal.

Six different names were put into a hat. A name is chosen 125 times and the name Grace is chosen 17 times. What is the experimen

Elodia [21]

Answer:

Step-by-step explanation:

The experimental probability of choosing Grace is 13.6% (17/125*100)

The theoretical probability of choosing Grace is 16.67% (1/6)

Each probability would change because they depend on the data set so if the data set changes, that means the probability will also change depending on the amount it changes.

Political parties rely heavily upon polling to measure their support in the electorate. In a country with four major political p

liberstina [14]

Answer:

a) The claim is not plausible

b) claim is plausible and the type of bias here is response bias

Step-by-step explanation:

Given data:

Number of political parties = 4

coffee party got the support of 435 out of 1183 randomly selected voters in a poll conducted.

A) Construct and interpret a 98% confidence interval to estimate the proportion of voters who support the coffee party

H0 ( null hypothesis ) : p = 0.42

Ha ( alternate hypothesis ) : p ≠ 0.42

z value for 98% confidence interval = 2.326

using 98% confidence interval the value of p = ( 0.3668, 0.3686 )

hence the claim is not plausible

B) Determine the type of bias

Assume the actual number of people = 1200

and 17 people did not respond

hence number of people who responded = 1200 - 17 = 1183

Therefore the claim by the manager is plausible because 17 people did not respond and the type of bias here is response bias

attached below is a detailed solution of the problem of the A part
