Transcribed Image Text:"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:
Ο Ho: μ < 0.3
H : μ > 0.3
Ho:μ = 0.3
H : μ = 0.3
Ο Ho: μ 2 0.3
Hy: μ < 0.3
Ho:p ≤ 0.3
H₁:p> 0.3
O Ho:p≥ 0.3
H₁:p < 0.3
○ Ho: p = 0.3
H₁:p 0.3
The null hypothesis in words would be:
O The proportion of people in a sample that prefers Trydint gum is 0.3.
O The average of people that prefer Trydint gum is not 0.3.
O The proportion of all people that prefer Trydint gum is greater than 0.3.
O The proportion of all people that prefer Trydint gum is less than 0.3.
O The average of people that prefer Trydint gum is 0.3.
O The proportion of people in a sample that prefer Trydint gum is not 0.3
O The proportion of all people that prefer Trydint gum is 0.3
Based on a sample of 80 people, 19 said they prefer "Trydint" gum to "Eklypse".
The point estimate is:
The 90 % confidence interval is:
