Answer:
The decision rule for rejecting H0 is if the test statistic falls outside the region bounded by the critical values.
Explanation:
Null hypothesis: The actual percentage that do not fail is the same as the stated percentage.
Alternate hypothesis: The actual percentage that do not fail is different from the stated percentage.
Test statistic (z) = (p' - p) ÷ sqrt[p(1-p) ÷ n]
p' is sample proportion = 0.51
p is population proportion = 0.48
n = 1700
z = (0.51 - 0.48) ÷ sqrt[0.48(1-0.48) ÷ 1700] = 0.03 ÷ 0.012 = 2.5
The test is a two-tailed test. At 0.01 significance level, the critical values are -2.576 and 2.576
Decision rule:
Reject H0 (null hypothesis) if the test statistic falls outside the region bounded by the critical values -2.576 and 2.576.

<em>5. Marketing Research.</em>
Explanation:
Market research <em>offers useful information to help overcome certain marketing problems that sometimes a company would most probably face— an essential component of the business planning process. </em>
In reality, it is impossible to construct techniques including market segmentation (classifying particular groups within the same sector) and product differentiation (creating an identity for a product or service that separates it from competitors) without marketing research.
A manufacturing process requires small amounts of glue. the glue used in the production process is classified as an indirect material.
What is indirect material?
Even though they are used in the entire manufacturing process, indirect materials do not go into the finished product. For instance, while disposable gloves, PPE, tape, etc. may be necessary for a production line, the actual product produced on that line may not include any of these items.
Therefore,

Answer:
8.89%
Explanation:
The answer is 8.89%
Here is how we arrived at this.
Dividend = 1$ times 4
= $4 annually
Then we calculate for the nominal rate of return.
This is equal to dividend / price.
= $4/ $45
= 0.0889
To convert this to percentage
0.089 x 100
= 8.89% is the nominal annual rate of return.
