Given:
value of the test statistic is t20 = 1.95
corresponding p-value of 0.0653 at the 5% significance level

No, I can't conclude that the correlation coefficient differs from zero because the p-value, which is 0.0653 exceeds 0.05. 

The correlation coefficient differs from zero when the p-value is less than 0.05.

WILL GIVE BRAINLIEST!!!!!
Temka [501]

The value of x from the given line segment is 1 2/3.

Given that, line segment AC = 5 and line segment AB = 3x - 5.

We need to find the value of x.

<h3>What is the line segment?</h3>

A line segment is a part of a line that has two endpoints and a fixed length. It is different from a line that does not have a beginning or an end and which can be extended in both directions.

Since point B is the midpoint of the line segment AC.

AB=BC=3x - 5

Now, AC=AB+BC

⇒5=3x - 5+3x - 5

⇒6x=15

⇒x=15/6

⇒x= 5/3

⇒x=1 2/3

Therefore, the value of x from the given line segment is 1 2/3.

What is the mean of the data set?
mestny [16]

Ok, im guessing that this is all about mean

First mean is just adding everything up for example:

5+5+10+10+5

so the answer is 35, but that isnt completely finished you need to divide 35 by 5, or how many numbers were added then you get the mean for my example the mean is 7

------------------------------------------------

ACTUAL PROBLEMS

1. 10+15+14+8+18+11+12+12+10+10+17+16 = 153

153/12= 12.75

2. 16.4+17.1+17.4+18.1= 69 B)

69/4=17.25

3.  11+15+19+17+23+20+17+13+18+21=174

174/11=15.8181818182

4. 21+25+36+16+32= 130

130/5=26

According to the table below, what is the probability that the grade of a student chosen at random will be a B or higher? Grade
Nat2105 [25]

Answer:

1 / 7

Step-by-step explanation:

Given the distribution above :

P(grade B or higher) can be defined explicitly as :

P(Grade A) + P(Grade B)

P(grade A) = 2/35

P(Grade B) = 3 / 35

Hence,

P(Grade B or higher) = 2/35 + 3/35 = 5/35 = 1/7
