Option D.) a reflection over the y-axis and then a translation down by 5 units.
Answer:
1) test is one tail hypothesis test.
2) 110 sampled customers must have favored Coke.
3) at 5% significance, We cannot conclude that the proportion of customers who prefer Coca-Cola exceeds 50%.
4) at 1% significance level, the conclusion would not change.
Step-by-step explanation:
1) Let p be the proportion of customers who prefer Coke to other brands
Since the alternative hypothesis claims p <em>more than</em> 0.50, this test is one tail hypothesis test.
2) Out of a random sample of 200 consumers, 55% favored Coca-Cola over other brands. Thus 200 × 0.55 = 110 sampled customers must have favored Coke.
3) at 5% significance level, p-value =0.07761 >0.05, therefore we fail to reject the null hypothesis. We cannot conclude that the proportion of customers who prefer Coca-Cola exceeds 50%.
4) at 1% significance level, p-value =0.07761 >0.01, thus the conclusion does not change

Determine the additive inverse of each
The rule of additive inverse is as follows;
Using the above, the solution is as follows:
Rule: <em>6 becomes -6 and - (-3) becomes +(-3)</em>
So, the additive inverse is
<em />
Rule: <em>-6 becomes 6 and -3 becomes 3</em>
So, the additive inverse is
Rule: <em>6 becomes -6 and -3 becomes 3</em>
So, the additive inverse is
Rule: -<em>6 becomes 6 and -(-3) becomes +(-3)</em>
So, the additive inverse is
<em />
