A i did this and i got a good grade
The probability the pitch over the plate is a ball is 5:10. (5 balls and 10 strikes over the plate) should be written as 5:15 or 1:3 so this one is inaccurate.
Well, the 2 in 582 is in the ones place and the 2 in528 is in the tens place so
2 and 20
one is 10 times the other
they are both multiples of 2
one is a prime number and the other is a compsite
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

Y' = -2x+a
0 = -2(3)+a
6=a
8=-(3)^2 +(3)(6)+b
