Answer:
We can reject the null hypothesis. There is significant evidence that p<0.31 at α = 0.01
Step-by-step explanation:
To test the the claim p < 0.31, null and alternative hypotheses are:
: p=0.31
: p<0.31
For α = 0.01, one tailed test critical value is -2.33
For z=-3.36 , p value is ≈ 0.0004
Since p-value<significance level (0.0004<0.01), we can reject the null hypothesis. There is significant evidence that p<0.31 at α = 0.01
Answer:
The amount of discount is $120
The sale price is $480
Step-by-step explanation:
The amount of discount = Original price × the Percentage off
The amount of discount = $600 × 20 %

The amount of discount = $120
The sale price = Original price - Discount
The sale price = $600 - $120
The sale price = $480
