Question

For problems 9, 10, 11, and 12, solve the problems by answering a) State the claim (use a sentence), b) H., H, and place the claim with either one of the two. c) Test statistic, show and label the formula you use. d) Find critical value(s), and reject Ho or fail to reject Ho. You may use a p-value. e) Write a formal conclusion and final statement.

​​​​​​​Please show hand written work for everything including formulas etc.

Answer 1

solution, ituloa Given that it n=50 x= 27 SO p=* = 27 -0.54 Po = 65 do 20.65 Ho: p = 0.65 Haip 20.65 This is right -tailed test Test statistic, z = ².po Troll-po) = 0.54-0.65 0.65 (-0.65) 50 Z . -1.631 the test statistic =-1.631

the critical value = 1.64 P-value = 0.9485 0.9485 >0.05 P-value > < fail to reject the null hypothesis, - conclusionia - the null hypothesis Ho is not rejected There is not enough evidence to claim that the population proportion pic greater than po, at the 2-0.05 significance level.
