Question 1040365
"Using your data from 50 tosses, test the claim that the population proportion of Kisses chocolates that land completely on the base IS 50% at a=10% level of significance." (We tossed the candies and the total # is 13 kisses that landed on the base) 
C. Determine standardized test statistic
--------
p-hat = 13/50
z(13/50) = (13/50 - 0.5)/sqrt[0.5*0.5/50] = -3.6770
D. Find P-value::
Since Ha is p = 0.5
p-value = 2*p(z < -3.6770) = 2*normalcdf(-100,-3.6770) = 0.0002361..
