We know that, the general equation of the parabola.
Substitute the value of in equation
and find the value of
Hence, the equation of the parabola is:
Answer:
t = 2.2450
d. 0.264
Step-by-step explanation:
The null hypothesis is:
Alternative hypothesis;
The pooled variance t-Test would have been determined if the population variance are the same.
The t-test statistics can be computed as:
t = 2.2450
Degree of freedom
df = (8-1)+(8-1)
df = 7 + 7
df = 14
At df = 14 and ∝ = 0.05;
Decision Rule: To reject the null hypothesis if the t-test is greater than the critical value.
Conclusion: We reject and there is sufficient evidence to conclude that the test scores for contact address s less than Noncontact athletes.
To calculate r²
The percentage of the variance is;
