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.

I need assistance with finding Z AND P VALUE. If you could guide me through the steps
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. You may need to use the appropriate table in the Appendix of Tables to answer this question. Submit Answer X w 12 MacBook Air 000 >> F11 F12 esc 000 F4 F10 0 A F5 F7 F8 F9 F1 F2 F3
