hmm that website doesnt seem to work..

jan o2 6d is a normal hypothesis test
H0: p = 0.4
H1: p > 0.4
Binomial (10, 0.4)
P(X>8) = 1 - P(X \< 7) = 0.0123
0.05 > 0.0123, therefore the result is significant so reject null hypothesis and accept alternative hypothesis
i.e. enough evidence to suggest that number of ppl who prefer organic is higher than the magazine's claim

I hope this helps...i think i do hypothesis testing a different way from some people
