Answer: We reject the null hypothesis.

Step-by-step explanation:

Given : Significance level : \alpha=0.01

Let p represents the proportion of the settled medical malpractice suits.

Given claim : The percentage of settled medical malpractice suits is at least 50%.

i.e. p\geq 0.5

Thus,

H_0:p\geq0.5\\\\H_a:p

We know that when the calculated p-value is less than the significance level (\alpha) then we reject the null hypothesis, if p-value is greater than the significance level (\alpha) then we do not reject.

Now , the calculated value 0.012 is less than the 0.01, so we reject the null hypothesis.

Answer:

<u>First Part:</u>  Hannah will pay $45.25

<u>Second Part:</u>  Hannah will pay $46.75

Step-by-step explanation:

<u>Complete Question:</u>

<em>Hannah was shopping for a summer dress at a store near her home. On the rack where she found the dress she wanted, she saw two signs. The first one read, “Clearance: 15% off.” The second one read, “$10 off—Instant Savings.” The original price of the dress was $65.00. Hannah lives in Oregon, where there is no sales tax. </em>

  • <em> How much will Hannah pay for the dress if the 15% discount is applied before the $10 discount? </em>
  • <em> How much will Hannah pay for the dress if the $10 discount is applied before the 15% discount?</em>

<em />

<u>First Part:</u>

First, 15% off, then $10 off. So

65 - (0.15)(65) = $55.25

Now $10 off makes it:

55.25 - 10 = $45.25

Hannah will pay $45.25

<u>Second Part:</u>

Now, first we have to apply $10 discount, so:

65 - 10 = $55

Now, we apply 15% discount, thus:

55 - (0.15)(55) = $46.75

Hannah will pay $46.75
