Walk is a 90 degree angle because of the angle marker

Bus is given

360-90 gives the total for bike,bus,car
=270-120= 150 (120 is from the given)

150 is what is left for bike and car
I say your best is to divide that by 2 but you don’t know the exact degree but those two seem pretty well even so 150/2= 75 aka 75 for both bike and car


Now that you know the degrees you have to find the percents. 360=1 circle

Walk=90/360=.25•100=25%

Bus=120/360=.33•100=33%

Bike=75/360=.208•100=21% (rounded)

Car is the same as bike=21%

Add up percents and it should add up to 100 to check.

Now back to the decimals. Sorry for the inconvenience.

Use .25•(total number of pupils)=9 pupils that walked.

Do that for each one and at the end all your answers for the boxes should add up to 36

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.
