Question
Transcribed Image Text:"Trydint" bubble-gum company claims that 7 out of 10 people prefer their gum to "Eklypse". Test their claim
at the 99 confidence level.
The null and alternative hypothesis in symbols would be:
Ho: p = 0.7
H₁: p = 0.7
OT
Ο Ho : μ < 0.7
H : μ > 0.7
Ο Ηo : μ = 0.7
H₁:μ 0.7
Ho: p≥ 0.7
H₁: p < 0.7
Ho: p ≤ 0.7
H₁: p > 0.7
Ο Ho : μ 2 0.7
H : μ < 0.7
The null hypothesis in words would be:
The proportion of all people that prefer Trydint gum is 0.7
O The proportion of people in a sample that prefers Trydint gum is 0.7.
O The proportion of people in a sample that prefer Trydint gum is not 0.7
O The average of people that prefer Trydint gum is not 0.7.
The average of people that prefer Trydint gum is 0.7.
O The proportion of all people that prefer Trydint gum is greater than 0.7.
O The proportion of all people that prefer Trydint gum is less than 0.7.
Based on a sample of 130 people, 77 said they prefer "Trydint" gum to "Eklypse".
The point estimate is:
(to 3 decimals)
The 99 % confidence interval is: 0.480
Based on this we:
Fail to reject the null hypothesis
Reject the null hypothesis
O to
(to 3 decimals)
