The statistician has two independent random samples of dogs from two different geographical locations and has recorded the proportion of dogs that shed in each sample.

B
A campaign manager would like to show that the distribution of individuals within several social economic categories is different than what a newspaper reported. The campaign manager has a random sample of potential voters in a large city and records the number of individuals within each of the categories.

A manager of a water treatment plant would like to investigate whether there is a relationship between the amount of chemical used and the number of bacteria present in the water treated at the plant. The manager measures the level of bacteria from tanks at the facility that each received a different level of chemical treatment.

D
City officials would like to estimate the average price of gas in their city. The officials have a random sample of gas prices at several gas stations within their city limits.
A campaign manager would like to show the distribution of individuals...
Step-by-step explanation:
goodness of fit can be used to compare observed and expected counts. The newspaper report would be the expected. The campaign manager's distribution is the expected.
If the discount is 30%, we can find the discounted price by taking 70% of the original price (since 100% - 30% = 70%). Substitute the equivalent 0.70 to calculate the discount price: 0.70($24.50) = $17.15. This is the discounted price.
The final cost is $17.15 times 1.07, which includes the discounted price plus the 7% tax. That final cost is 1.07($17.15) = $18.35.
The lateral area of the prism is given by: LA=[area of the two triangles]+[area of the lateral rectangles] hypotenuse of the triangle will be given by Pythagorean: c^2=a^2+b^2 c^2=6^2+4^2 c^2=52 c=sqrt52 c=7.211' thus the lateral area will be: L.A=2[1/2*4*6]+[6*8]+[8*7.211] L.A=24+48+57.69 L.A=129.69 in^2
The total are will be given by: T.A=L.A+base area base area=length*width =4*8 =32 in^2 thus; T.A=32+129.69 T.A=161.69 in^2
