castortr0y [4]

Answer:

The claimed proportion (population) is

p=0.11

The sample proportion (p-hat) is

\hat{p}=0.10

Step-by-step explanation:

In the population, we have the parameter p that is 11%.

p=0.11

Then, a sample of n=160 is taken and the proportion of the sample is 0.10.

\hat{p}=0.10

The sample proportion p-hat can differ from the population's proportion. There is a sampling distribution that gives the possible values of the sample proportion taken out of this population and its associated probabilities.

On Monday, the high was 60oF. On Tuesday, the high was 10% more than Monday. Then on Wednesday, the temperature decrease by 8%.
Arada [10]

Answer:

60.72

Step-by-step explanation:

Monday: 60 degrees

Tuesday: temperature increases by 10 percent

60 + 10% of 60

60 + .10*60 = 70 +6 = 66

Wednesday: temperature decreases by 8 percent

66 - 8%of 66

66 - .08*66 = 66 -5.28=60.72
