uppose that a single die with 8 sides (numbered 1, 2, 3, ... , 8) is rolled twice. What is the probability that the sum of the t
1 answer:
Answer:
1/16 = 0.0625 = 6.25% probability that the sum of the two rolls equals 5.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Die with 8 sides
This means that the total number of outcomes is
Outcomes in which the sum of the two rolls is 5:
(1,4), (4,1), (2,3), (3,2)
4 desired outcomes, so
What is the probability that the sum of the two rolls equals 5?
1/16 = 0.0625 = 6.25% probability that the sum of the two rolls equals 5.

Answer:
a) P=0.03
b) α=0.05
c) 0.72
d) 100
e) 0.72
Step-by-step explanation:
a) The P-value is the probability of the sample result. In this case the P-value is 0.03.
b) The level of significance is the threshold of probabilty for the null hypothesis to be reejcted or not. It is contrasted with the P-value to know if the effect is significant. In this case, the level of significance is 0.05.
NOTE: if it is a two-side test, the level of significance is 0.1 (two times 0.05).
c) The sample proportion is the one that results from the sample data. In this case, the sample proportion is 0.72.
d) The sample size is the amount of consumers reported. In this case is 100 customers.
e) The null value is 0.72 (equal to the sample proportion), because it is tested if there is no difference between the population proportion and the sample proportion.

D).
To express polynomial with mixed variables in standard form, we begin by the highest coefficient of x to the smallest (we place high precedence on the coefficient x terms)
