Determine the sample proportion. b. Decide whether using the one-proportion z-test is appropriate. c. If appropriate, use the one-proportion z-test to perform the specified hypothesis test Click here to view a. The sample proportion is Type an integer or a decimal Do not round)Explanation / Answer
a) Sample praportion=x/n
=8/40
=0.20
b)
Test and CI for One Proportion
Test of p = 0.3 vs p not = 0.3
Sample X N Sample p 90% CI Z-Value P-Value
1 8 40 0.200000 (0.095970, 0.304030) -1.38 0.168
c)Now pvalue > alpha
