..11 Verizon MENU Courses 9:11 PM i webwork.pcc.edu bon ewokSignificance Testing: Problem 6 Sets Previous Problem Problem List Next Problenm (1 point) Albert thinks that he has a special relationship with the number 4. In particular, Albert thinks that he would roll a 4 with a fair 6-sided die more often than you'd expect by chance alone. Suppose p is the true proportion of the time Albert will roll a 4 User Grades (a) State the null and alternative hypotheses for testing Albert's claim. (Type the symbol "p" for the Achievements population proportion, whichever symbols you need of

Explanation / Answer

a)
Ho: p = 1/6
Ha: p > 1/6       {if Ha is wrong try Ha p >= 1/6}

b)
X = 11 , n = 50
Test and CI for One Proportion

Test of p = 0.166667 vs p > 0.166667

Sample   X   N Sample p 95% Lower Bound Z-Value P-Value
1       11 50 0.220000         0.123639     1.01    0.156

Using the normal approximation.

p-value = 0.156

c)
since p-value > 0.05
we fail to reject Ho
hence
No
