<h2><<< In this case, the mode is 9 seconds. The median is the middle number in a list of numbers ordered from smallest to largest. so 10 is the median of this set of results. The range is the difference between the lowest value and the highest value, so the range here is 15 - 9 = 6. </h2>
Answer:
Q' (-2, 2)
P' (-2, 7)
R' (6, 2)
Step-by-step explanation:
When reflecting over a diagnal line such as y = x or y = -x, a trick is to count the boxes at an angle to see how many spaces it is away from the line. Be sure to recipicate what you counted the first time, and when reflecting over y = -x, flip the x and y coordinates and if needed, change the signs.
Hope this helps!
Answer:
Test: 
< 20 with normal distⁿ
Hypothesis test:
H0: 
20 (Null Hypothesis, H₀ : = 20 is also correct)
H1: < 20 (Alternative Hypothesis, also called H₁)
This is lower tailed test.
Since sample is large, sample standard deviation can be taken as an approximation of population standard deviation.
x = 19.3
= 11.1
n = 444
significance level, 
= 0.05 (If no value is given, we take level of 0.05)
Test statistic 
= - 1.33
