Answer:
A) H0: μ = 11 vs. Ha: μ > 11
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean. While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
Therefore, for the case above;
The null hypothesis is that the average number of headaches per student during a semester of Statistics is 11.
H0: μ = 11
The alternative hypothesis is that the average number of headaches per student during a semester of Statistics is greater than 11.
Ha: μ > 11
-4x+3y=15
3y=15+4x
y=(15+4x)/3= 4/3x +5
slope: 4/3
y-intercept: 5
