Question

"Trydint" bubble-gum company claims that 3 out of 10 people prefer their gum to "Eklypse". Test their claim at the 90 confidence level.

The null and alternative hypothesis in symbols would be

H0:p=0.3
H1:p≠0.3

The null hypothesis in words would be:

The proportion of all people that prefer Trydint gum is 0.

Based on a sample of 100 people, 25 said they prefer "Trydint" gum to "Eklypse".

The point estimate is: 0.250

The 90 % confidence interval is: to (to 3 decimals)

Based on this we:

Reject the null hypothesis
Fail to reject the null hypothesis
