We can’t see the graph or the picture it’s supposed to represent
Answer:
Option C
Step-by-step explanation:
n = 81
s2 = 625
H0: σ2 = 500
Ha: σ2 ≠ 500
Test Statistics X^2 = (n-1)s^2/ σ2 = (81-1)*625/500
X^2 = 100
P value = 0.0646 for degree of freedom = 81-1 = 80
And X^2 = 100
At 95% confidence interval
Alpha = 0.05 , p value = 0.0646
p < alpha, we will reject the null hypothesis
At 95% confidence, the null hypothesis
Table m I believe because each x has one y
Dividing by 5 is equivalent to dividing by 10 and then multiplying by 2.
therefore:
63.5/5 = (63.5/10) * 2 = 6.35 * 2 =12.70 which rounds to 13.
