Answer:
a
The correct option is B
b
The correct option is D
Step-by-step explanation:
From the question we are told that
The level of significance is
The p-value is
Considering question b
Given that the then the null hypothesis is rejected
Considering question b
Given that the original claim is The standard deviation of pulse rates of a certain group of adult males is more than 11 bpm
Then the null hypothesis is
The reason why the null hypothesis is write like this above is because a null hypothesis expression can not contain only a > or a < but only allows =
and the alternative hypothesis is
Now given that the null hypothesis is rejected, it mean that there is sufficient evidence to support original claim
Answer:
The solutions are:
and 
Explanation:
The general form of the quadratic equation is:
ax² + bx + c = 0
The given equation is:
2x² - 6x + 5 = 0
By comparison:
a = 2
b = -6
c = 5
Now, to get the solutions of the equation, we will have to use the quadratic formula shown in the attached image.
By substituting in the formula, we would find that:
either x =
or x =
Hope this helps :)
