Hypothesis Tests

Question 1

Statistical hypothesis testing using a binomial distribution

Answer 1

• H0 : p=x
• H1 : p>x, p<x, p/=x
• if calculated probability < significance level, reject H0

Question 2

Statistical hypothesis testing using a normal distribution

Answer 2

• H0 : mew=x
• H1 : mew>x, mew<x, mew/=x where mew is the mean population value
• if p-value < significance level, reject H0

Question 3

Correlation and association hypothesis tests

Answer 3

• H0 : row=0
• H1 : row>0, row<0, row/=0 where row is the population product moment correlation coefficient
• r is the sample correlation coefficient
• if r>CV, reject H0

Question 4

Chi-squared hypothesis tests

Answer 4

• H0 : no association
• H1 : some association
• if chi squared > CV, reject H0
