In manufacturing, convenience sampling could be used to determine if the machines are operating correctly. Which of the following best describes this type of sampling?Every 10th product in the line is selected
Samples are randomly selected throughout the day
Products are put into groups and all are included from several randomly selected groups
Products are put into groups and some are randomly selected from each group
Answers
Answer:
Every 10th product in the line is selected
Step-by-step explanation:
Convenience sampling also available sampling, or nearest in reach sampling.
it is a type of non-probability sampling that involves the sample being drawn from a population that is in reach or that is easily at hand.
example. A questionnaire being distributed to people met in a mall.
for the manufacturing company in question, the first 10 product in line were the first set of product the machine will produce (at hand).
it is normally use to test run the operation of the machine.
Final answer:
Convenience sampling in manufacturing is best described as selecting every 10th product in the line for testing. It is a simple, quick, and cost-effective way to identify potential issues.
Explanation:
In the context of manufacturing, convenience sampling represents a type of sampling where samples are chosen because they are readily available or easy to obtain. In the provided choice list, the best description of convenience sampling is 'Every 10th product in the line is selected'. This method is chosen for its simplicity and speed. While it may not provide a comprehensive result since it won't cover all the various different scenarios, it is a cost-effective and time-efficient way of identifying potential issues in machine operations.

Answer:
(a) The critical value of t at P = 0.01 and 15 degrees of freedom is 2.602.
(b) The critical value of t at P = 0.05 and 19 degrees of freedom is -1.729.
(c) The critical value of t at P = 0.025 and 12 degrees of freedom is -2.179 and 2.179.
Step-by-step explanation:
We have to find the critical t values for each of the following levels of significance and sample sizes given below.
As we know that in the t table there are two columns. The horizontal column is represented by the symbol P which represents the level of significance and the vertical column is represented by the symbol '' which represents the degrees of freedom.
(a) A right-tailed test of a population mean at the α=0.01 level of significance with 15 degrees of freedom.
So, here the level of significance = 0.01
And the degrees of freedom = n - 1 = 15
Now, in the t table, the critical value of t at P = 0.01 and 15 degrees of freedom is 2.602.
(b) A left-tailed test of a population mean at the α=0.05 level of significance with a sample size of n = 20.
So, here the level of significance = 0.05
And the degrees of freedom = n - 1
= 20 - 1 = 19
Now, in the t table, the critical value of t at P = 0.05 and 19 degrees of freedom is -1.729.
(c) A two-tailed test of a population mean at the α=0.05 level of significance with a sample size of n = 13.
So, here the level of significance = = 0.025 {for the two-tailed test}
And the degrees of freedom = n - 1
= 13 - 1 = 12
Now, in the t table, the critical value of t at P = 0.025 and 12 degrees of freedom is -2.179 and 2.179.

The volume of the tower is 224 in³, which is not listed among the given options.
To find the volume of the rectangular block, we need to multiply its length, width, and height. Therefore, the volume of the single block is:
8 x 3.5 x 2 = 56 cubic inches.
Since we are stacking four blocks to create a tower, we need to multiply the volume of a single block by 4.
Thus, the volume of the tower is:
56 x 4 = 224 cubic inches.
The volume of a rectangular block can be found using the formula,
V = length × width × height.
In this case, the length is 8 inches, the width is 3.5 inches, and the height is 2 inches.
V = 8 × 3.5 × 2 V
= 28 × 2 V
= 56 in³
Now that we know the volume of one block, we can find the volume of the tower created by stacking four blocks. Tower volume = block volume × number of blocks Tower volume = 56 in³ × 4 Tower volume = 224 in³
