This is indeed a linear equation. y-4x=9 in standard form is y=4x+9.
Answer:
maximum 5 CDs
Step-by-step explanation:
Let Mitchell can order a maximum of x CDs
It has been given that each CD costs $15.99, and shipping for the entire order is $9.99.
Thus, we have the total cost for x CDs
Now, Mitchell has no more than $100 to spend. It means
Subtract 9.99 to both sides
Divide both sides by 15.99
Hence, Mitchell can order maximum 5 CDs
Answer:
(a) P-value = 0.074, α = 0.05 do not reject H0
(b) P-value = 0.006, α = 0.001 do not reject H0
(c) P-value = 0.494, α = 0.05 do not reject H0
(d) P-value = 0.074, α = 0.10 reject H0
(e) P-value = 0.028, α = 0.01 do not reject H0
(f) P-value = 0.296, α = 0.10 do not reject H0
Step-by-step explanation:
The p-value is used to determine the statistical significance of the results of a statistical test. The p-value is the probability that the null hypothesis is correct. Smaller the p-value, higher is the probability that the alternate hypothesis is correct. On the other hand, the significance level (α) is the probability of rejecting the null hypothesis when it is true. It is the risk that you are willing to take in saying that there are differences between groups when there are not.
In order to reject the null hypothesis, the p-value should be lower than the significance level (α).
