"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 one of these:
H0:p=0.7
H1:p≠0.7
H0:p≥0.7
H1:p<0.7
H0:p≤0.7
H1:p>0.7
H0:μ≤0.7
H1:μ>0.7
H0:μ=0.7
H1:μ≠0.7
H0:μ≥0.7
H1:μ<0.7
The null hypothesis in words would be one of these:
The average of people that prefer Trydint gum is 0.7.
The proportion of all people that prefer Trydint gum is less than 0.7.
