Alaina wants to decide whether her current cell phone plan is better than a package that another company offers. To compare the

laiz [17]

Hello, this is a linear problem so we are working with y = mx + b

The problem tells us:

y = total cost

x = the megabytes of data that she used in a month

b = y-intercept, which is the initial value

The problem asks "Which part of the graph will represent the cost per megabyte of data used in each plan?"

It is asking for cost per megabyte... This is a rate. and m = slope = rate

So lets, reiterate.

y = total cost

x = the megabytes of data that she used in a month

b = y-intercept, which is the initial value

m = slope = rate = cost per megabyte of data used

Answer: The slopes of the two lines.

Mademuasel [1]

Answer:

Claim is true that most medical malpractice lawsuits are dropped or dismissed.

Step-by-step explanation:

Given :In a study of 799 randomly selected medical malpractice lawsuits, it was found that 499 of them were dropped or dismissed.

To Find : Use a 0.05 significance level to test the claim that most medical malpractice lawsuits are dropped or dismissed.

Solution:

n = 799

x = 499

We will use one sample proportion test

$\widehat{p}=\frac{x}{n}\\\widehat{p}=\frac{499 }{ 799}\\\widehat{p}=0.6245$

We are given that the claim is most medical malpractice lawsuits are dropped or dismissed.

Probability of dropped or dismissed is 1/2

$H_0:p=0.5\\H_a:p>0.5$

Formula of test statistic = $\frac{\widehat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}$

= $\frac{0.6245-0.5}{\sqrt{\frac{0.5(1-0.5)}{799}}}$

= 7.038

p value (z>7.038) is 0

α =0.05

So, p value < α

So, we reject the null hypothesis

So,claim is true

Hence most medical malpractice lawsuits are dropped or dismissed.
