We have given,
The population variances are not known and cannot be assumed equal.
The test statistic for the test is

Where,
= sample meaan of population 1
= sample mean of population 2
= sample size of population 1
= sample size of population 2
Therefore, this is the test

Answer:
a. y=x+1
b. x=-3
Step-by-step explanation:
a. slope= (6-4)/(5-3)=1
substitute (5,6) to y=1x+b; b=1
therefore, y=x+1
b. x=-3
The probability that it strikes Texas given that it strikes the US will be "0.071".
Given that,
The total area of US,
- P(U) = 3.79 million square miles
Area covered be Taxes,
- P(T) = 0.27 million square miles
According to the Baye's theorem,
→ 
By substituting the values, we get
→ 
→ 
Thus the above answer is correct.
