Answer:

Second plot (bottom of middle picture)

Step-by-step explanation:

Rewrite the data points in ascending order.

5 5 5 5 5 5 6 6 6 8 8 8 9 10 10 11

There are 6 data points of 5 cm.

There are 3 data points of 6 cm.

There are 3 data points of 8 cm.

There is 1 data point of 9 cm.

There are 2 data points of 10 cm.

There is 1 data point of 11 cm.

Now look at the plots, and see which one matches those values.

The second plot matches the data.

A sprinkler system is being installed in a newly renovated building on campus. The average activation time is supposed to be at
melomori [17]

Answer:

A) t = 1.73

B) p-value =  0.0558

C) Data is not statistically significant because the p-value of 0.0558 is more than the significance value of 0.05

D) The decision means that the design specifications are not met.

E) Type II error

Step-by-step explanation:

The hypotheses are:

H₀: μ = 20

H₁: μ > 20

A) Formula for the test statistic is;

t = (x' - μ)/(s/√n)

Now, we are given;

x' = 21.5

μ = 20

s = 3

n = 12

Thus;

t = (21.5 - 20)/(3/√12)

t = 1.73

B) we have our t-value as 1.73

Now, Degree of freedom(DF) = n - 1

So,DF = 12 - 1 = 11

Using significance level of α = 0.05, t-value = 1.73 and DF = 11, one tailed hypothesis, from online P-value calculator attached, we have;

p-value =  0.0558

C) Data is not statistically significant because the p-value of 0.0558 is more than the significance value of 0.05

D) We will not reject the null hypothesis. The decision means that the design specifications are not met.

E) If the true average activation time of the sprinkler system is, in fact, equal to 20 seconds, then the null hypothesis is false.

Since we did not reject the null hypothesis even though it is false, the error that was committed was therefore a type II error.

Complete the point-slope equation of the line through (1,-1)(1,−1)left parenthesis, 1, comma, minus, 1, right parenthesis and (5
goldenfox [79]

Answer:

<h3>y+1 = 3/4(x-1)</h3>

Step-by-step explanation:

Given the coordinates of a line, (1, -1) and (5, 2), we are to find the equation of the line in point-slope form.

The point slope form of the equation is generally expressed as;

y -y0 = m(x-x0)

m is the slope

(x0, y0) is the point

Get the slope first;

m = y2-y1/x2-x1

m = 2-(-1)/5-1

m = 3/4

Substitute any of the point sat=y (1, -1) and m = 3/4 into the point slope form of the equation

y - (-1) = 3/4 (x-1)

y+1 = 3/4(x-1)

Hence the required equation is y+1 = 3/4(x-1)

Brian read 2/15 of his novel in 20 minutes.
VMariaS [17]

Answer:

Brian can read 0.4 or 4/10 in 1 hour

Step-by-step explanation:

The answer is 4/10 because 20 multiplied by 3 is 60, which equals 1 hour.

So, 2/15 times 3 = 4/10
