In a population, 11% of people are left handed. In a simple random sample of 160 people selected from this population, the proportion of left handers is 0.10. Denote the sample proportion (phat) and the claimed proportion (p0).

The claimed proportion (population) is

The sample proportion (p-hat) is

Step-by-step explanation:

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

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

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
