Answer:
25.05
Step-by-step explanation:
Given that a random sample of 160 car crashes are selected and categorized by age. The results are listed below. The age distribution of drivers for the given categories is 18% for the under 26 group, 39% for the 26-45 group, 31% for the 45-65 group, and 12% for the group over 65.
<26 26-45 46-65` >65
Observed O 66 39 25 30 160
Expected E 40 40 40 40 160
Chi square
(O-E)^2/E 16.9 0.025 5.625 2.5 25.05
Thus we get chi square test statistic = 25.05
18 would be the 7th so... hope it helps
Answer: Hello, where is the question here? The analysis is correct to a large extent. Please send me the requirement. Thank you
8+6/2=17-5
We can start by reducing the fraction using basic division.
Remember, numerator divided by denominator.
6 \ 2 = 3.
Rewrite the equation-
8+3=17-5
It doesn’t matter which side of the equal sign you start with, but in this case I started with the right hand.
8+3= 11
Rewrite-
11=17-5
Now subtract.
17-5=12
Write the equality.
11=12.
This is false.
11≠12.
