_{6. A researcher hypothesizes that individuals who listen to classical music will score differently from the general population on a test of spatial ability. On a standardized test of spatial ability, m 558. A random sample of 14 individuals who listen to classical music is given the same test. Their scores on the test are 52,59,63,65,58,55,62,63,53,59,57,61,60,59.}

a. Is this a one-or two -tailed test? the test is two-tailed. Because, the alternative hypothesis is that the average score of standardized test of spatial ability is different from 58%.
b. What are H0 and Ha for this study?
H0: µ = 58% That is, the average score of standardized test of spatial ability is 58%.
H1: µ ≠58% That is, the average score of standardized test of spatial ability is different from 58%.
c. Compute tobt. Here, the sample mean, x-bar is 59

d. What is the zcv?

e. Should H0 be rejected? What should the the researcher conclude?

f. Determine the 95% confidence interval for the population mean, based on the sample mean.
