Answer:

Step-by-step explanation:

Mean = Sum of data ÷ number of data set

$=\dfrac{9+3+15+7+2+4+3}{7}\\\\=\dfrac{43}{7}\\\\= 6.14\\\\= 6.1$

Median:

Arrange the data in ascending order:

2 , 3 , 3 , 4 , 7 , 9 , 15

Middle term is the median of the data set

Median = 4th term = 4

Mode:

Mode is the data whose is frequency is more.

So, mode = 3

Range = Maximum - minimum

= 15 - 2

= 13

A professor using an open source introductory statistics book predicts that 10% of the students will purchase a hard copy of the

Likurg_2 [28]

Answer: The professor was not accurate with his hypothesis.

Null hypothesis: P1 = 12.5%, P2 = 42.5%, P3 = 45%

The alternate hypothesis: At least one proportion of the student will differ from the others.

Step-by-step explanation: To check if the professors hypothesis were inaccurate.

What percentage of student bought a hard copy of the book.

(25 ÷ 200) × 100 = 12.5%

What percentage of the student printed it from the web.

(85 ÷ 200) × 100 = 42.5%

What percentage of the students read it online.

(90 ÷ 200) × 100 = 45%

This means that the professor was not accurate with his hypothesis. Because the proportion of student in his hypothesis was not the same in the actual.

Therefore; the null hypothesis are

P1 = 12.5%, P2 = 42.5%, P3 = 45%

The alternative hypothesis will state that at least one of the proportion will be different from the others.

Can anyone help me solve this

yawa3891 [41]

Answer:

a. $45.54; b. $51.42; c. See below

Step-by-step explanation:

a. 193 min

Service charge = $40.00

1st 100 min @ 0.021 = 2.10

Next 93 min @0.037 = 3.44

Total = $45.54

b. 317 min

Service charge = $40.00

1st 100 min @ 0.021 = 2.10

2nd 100 min @ 0.037 = 3.70

117 min @ 0.048 = 5.62

Total = $51.42

c. Piecewise function

The charge is

$40.00 + 0.021t if t ≤ 100
$42.10 + 0.037(t - 100) if 100 < t ≤ 200
$45.80 + 0.048 (t - 200) if t > 200

which we can write like this:

$f(t) =\begin{cases}40.00 + 0.021t & t \leq 100\\42.10 + 0.037(t-100) & 100 < t \leq200\\45.80 + 0.048(t-200) & t > 200\end{cases}$
