Find the correlation coefficient:
r=r= Round to 2 decimal places.
The null and alternative hypotheses for correlation are:
H0:H0: ? μ r ρ == 0
H1:H1: ? r ρ μ ≠≠ 0
The p-value is: (Round to four...

Directions: First, write a simple hypothesis.
State your hypothesis in such a way that it could be tested. Here
are some examples:
• Musical ability is an inherited trait.
• People who play video games for more than 2 hours every day are
