Arisa [49]3 years ago
5 0

Answer:

m = -6/7

b = -2

Step-by-step explanation:

m = (y2 - y1)/(x2 - x1) = (-2 - 4)/(0 - (-7)) = -6/7

y = mx + b

m = -6/7

y = -6/7 x + b

Use point (-7, 4).

4 = (-6/7)(-7) + b

4 = 6 + b

b = -2

y = -6/7 x - 2

m = -6/7

b = -2

"How much do students pay, on average, for textbooks during the first semester in college? From a random sample of 400 students
dezoksy [38]

Answer: The margin of error = 3.71, confidence interval = (354.04, 361.46) and it means that mean cost is lies within the confidence interval.

Step-by-step explanation:

Since we have given that

Sample size = 400

Mean = $357.75

Standard deviation = $37.89

At 95% confidence level, z = 1.96

We first find the margin of error.

Margin of error is given by

z\times \dfrac{\sigma}{\sqrt{n}}\\\\=1.96\times \dfrac{37.89}{\sqrt{400}}\\\\=3.71

95% confidence interval would be

\bar{x}\pm \text{margin of error}\\\\=357.75\pm 3.71\\\\=(357.75-3.71,357.75+3.71)\\\\=(354.04,361.46)

Hence, the margin of error = 3.71, confidence interval = (354.04, 361.46) and it means that mean cost is lies within the confidence interval.
