Q1) For sample size of 51 with standard deviation of 40, test claim that standard deviation of population is less than 53 using significance level of 0.05. Sketch a curve, point out the distribution (i.e., normal , student T, Chi square), critical region(s). test statistics, critical values(s) and n p-value:

Ho :   ...................   P-value=....................

H? :......................... Test stat =.................

CV=.................(critical value)

Reject/ fail to reject H μ

Q2) Test claim using both traditional and p-value methods that mean starting salary for college graduates is\$42.000. Results of survey of 31 graduates point out a mean salary of \$ 45,802 and standard deviation of \$7,300. Sketch a curve indicating distribution,(i.e. normal , student T, Chi square), critical region(s). p-value and illustrate the locations of test statistics and critical value(s). Use a significance oevel o f0.01.

Ho :   ...................   P-value=....................

H? :......................... Test stat =.................

CV=.................(critical value)
