Answer:
P-value is greater than the significance level, we fail to reject null hypothesis.
Explanation:
Here,
Sample size = n = 120
Sample proportion = p = 0.6500
Population Proportion = 
= 0.5
Level of significance = α = 0.02
<u />
<u>Step 1:
</u>
: p = 0.5
: p < 0.5 (Left tailed test)
<u></u>
<u>Step 2:
</u>
The critical vale is = 2.0537
<u></u>
<u>Step 3: </u>
The test statistic is,
z = 
<u>Step 5:
</u>
Conclusion using critical value: Since the test statistic value is greater than the critical value, we fail to reject null hypothesis.
<u>Step 6: </u>
Conclusion using P-value: Since the P-value is greater than the significance level, we fail to reject the null hypothesis.

Answer:
correct answer is Option D
Explanation:
Option D - elastic, and the demand curve will be horizontal.
The quantity would be changed infinitely with a samll change in the the price. It means that demand is perfectly elastic and the curve is horizontal as the small change up decreases the quantity to zero and small change down increases the quantity infinity. Thus, option D is the correct ams of this questionwer
Direct material cost variance = (Standard price - Actual Price) * Actual Quantity
= ($50 - $51) * 47,000
= $47,000 adverse
