there's no graph but the x axis is horizontal so look for the point closest to the horizontal line
Answer:
a) 21684
b) 15504
Step-by-step explanation:
a) Distribute the comic books as follows
only to 1 kid one way but we have five kids then 5
to two kids C₂₀,₂ = 20! /2! ( 20-2)! = 20*19 /2 = 190
To three C₂₀,₃ = 20! /3! ( 20 - 3)! = 20*19*18 /6 = 1140
To four C₂₀,₄ = 20 ! / 4! ( 20 - 4 )! = 20*19*18*17 /4*3*2 = 4845
To five C₂₀,₅ = 20! /5! (20 - 5 )! = 20*19*18*17*16/5*4*3*2*1
C₂₀,₅ = 15504
Then total ways of distribution are:
5 + 190 + 1140 + 4845 + 15504 = 21684
b) C₂₀,₅ we know from a that is equal to 15504
Answer:
(A) We failed to reject the null hypothesis
Step-by-step explanation:
Given that a high school teacher hypothesized that in her class, boys were taller than girls. If the probability value of her null hypothesis is 0.34, it means:
Here p value is 0.34
This is greater than 0.05 or 0.1 i.e. both for 5% significance and 10% significance.
Whenever p > alpha, we fail to reject null hypothesis
A) We failed to reject the null hypothesis
This would be the correct option
i.e. final conclusion is that there is no significant difference between mean height of girls and mean height of boys at 5% or 10% significance level.
The equation for the line would be Y=1/2x -2
