Ho: p ≤ 0.3
Ha: p > 0.3 (claim)
test stat: z = 1.41
.10 significance level, one-tailed
critical value = z = invNorm(.90) = 1.2845
P(z > 1.2845)...(area under the standard normal curve to the right of blue line represents the critical area)
1.41 > 1.28, reject Ho, accept claim

----
Since the altenate hypothesis is p > 0.3, you have a right-tail test.
------
Since the z-value for p = 0.3 is z = 1.41,
P value = P(z > 1.41) = normalcdf(1.41,100) = 0.0793
----------------------------------------
The critical value(s) is z = invNorm(0.99) = 2.3263
---------------
