About 10% of the human population Is left-handed. Suppose a researcher speculates that artists are more likely to be left-handed than other people in the general population. The researcher surveys 150 artists and finds that 18 of them are left-handed. If we use p to represent the proportion of all artists who are left-handed, the hypotheses are Ho: p - 0.10 and H p > 0.10. The sample result was that 18 artists of 150 surveyed (or 12%) are left- handed.

![About 10% of the human population is left-handed. Suppose a researcher speculates that artists are more likely to be left-handed than other people in the general population. The researcher surveys
150 artists and finds that 18 of them are left-handed.
If we use p to represent the proportion of all artists who are left-handed, the hypotheses are Ho: P - 0.10 and H: p> 0.10. The sample result was that 18 artists of 150 surveyed (or 12%) are left-
handed.
A USE SALT
(a) From the given information, do we know If the conditions necessary to use a z-statistic for this test are met? Explain.
We --Select-v sure the sample was selected randomly, the sample size-Select--v large enough because both np and n(1 - p) are
--Select-
v 10.
(b) State the population of interest, the population parameter of interest, and the value of the sample statistic.
The population of interest is -Select-
1. The population parameter is p = -Select-
The sample statistic is
(c) Conduct a hypothesis test using level of significance a = 0.05. Clearly give the details of the five steps. Be sure to write a conclusion.
Set up the null and alternative hypothesis.
Ho: P?v0.1
H:P?v0.1
Compute the test statistics for this situation. (Round your answer to two decimal places.)
Calculate the p-value for the test. (Round your answer to four decimal places.)
p-value =
On the basis of the p-value, make a conclusion for this situation.
<Select-
v because the p-value is-Select- v than 0.05.
Write a conclusion to this situation in words.
We -Select-v conclude that artists are more likely to be left-handed than people in the general population.
