b-2. Find the pvalue. O p-value < 0.01 O 0.01 s p-value < 0.025 O 0.025 s p-value < 0.05 O 0.05 s p-value < 0.10 O p-value 2 0.10 c. At the 5% significance level, What is the conclusion to the test? (Click to select) Hø, we (Click to select) conclude that x2 and x3 are jointly significant.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
![Consider a portion of simple linear regression results,
= 105.40 + 39.17x1; SSE= 4007,308; n= 30
In an attempt to improve the results, two explanatory variables are added. The relevant regression results are the following:
= 4.87 + 19.47x– 26.31×2 + 7.31x3;
SSE=344,784, n= 30.
[You may find it useful to reference the F table.]
a. Formulate the hypotheses to determine whether x, and x3 are jointly significant in explaining y.
O Ho: 62 = 63 = 0; HA: At least one of the coefficients is nonzero.
O Họ: 61 = 6, = 63 = 0; HA: At least one of the coefficients is nonzero.
O Ho: 62 = 63 = 0; HA: At least one of the coefficients is greater than zero.
b-1. Calculate the value of the test statistic. (Round intermediate calculations to at least 4 decimal places and final answer to 3
decimal places.)
