Course Hero The Pretty Pizza Company wants to open a new pizza place on either the north side of town or the south side of town.

They want to open the pizza place where the ratio of pizza places per person is less than 0.01. The population of 15 blocks of the north side of town is 225 people per block, and there are already 36 pizza places in the area. The population of 22 blocks of the south area is 275 people per block, and there are 37 pizza places in the area. Where, if anywhere, should the Pretty Pizza Company open a new pizza place

Answer:

The Pretty Pizza Company should open a new pizza place on the south area.

Step-by-step explanation:

The population of 15 blocks of the north side of town is 225 people per block, and there are already 36 pizza places in the area.

15*225 = 3375 people

36 pizza places

36/3375 = 0.0106 > 0.1

So not on the north side of the town.

The population of 22 blocks of the south area is 275 people per block, and there are 37 pizza places in the area.

22*275 = 6050 people

37 pizza places

37/6050 = 0.006 < 0.1

So, the Pretty Pizza Company should open a new pizza place on the south area.

In a sample of eight whitefish caught in Yellowknife Bay, the mean arsenic concentration in the liver was 0.32 mg/kg, with a sta
Advocard [28]

Answer:

The 95% confidence interval for the concentration in whitefish found in Yellowknife Bay is (0.2698 mg/kg, 0.3702 mg/kg).

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 8 - 1 = 7

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 7 degrees of freedom(y-axis) and a confidence level of 1 - \frac{1 - 0.95}{2} = 0.975. So we have T = 2.3246

The margin of error is:

M = T\frac{s}{\sqrt{n}} = 2.3646\frac{0.06}{\sqrt{8}} = 0.0502

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 0.32 - 0.0502 = 0.2698 mg/kg

The upper end of the interval is the sample mean added to M. So it is 0.32 + 0.0502 = 0.3702 mg/kg

The 95% confidence interval for the concentration in whitefish found in Yellowknife Bay is (0.2698 mg/kg, 0.3702 mg/kg).
