Answer:
a) Null and alternative hypotheses are:
: mu=183 days
: mu>183 days
b) If the true mean is 190 days, Type II error can be made.
Step-by-step explanation:
Let mu be the mean life of the batteries of the company when it is used in a wireless mouse
Null and alternative hypotheses are:
: mu=183 days
: mu>183 days
Type II error happens if we fail to reject the null hypothesis, when actually the alternative hypothesis is true.
That is if we conclude that mean life of the batteries of the company when it is used in a wireless mouse is at most 183 days, but actually mean life is 190 hours, we make a Type II error.

A. The ratio of soccer balls to all balls are 4:25
All the balls combined are 50 balls
8 of the balls are soccer balls so that makes the ration 8:50
In the simplest form it is 4:25 since you can't divide 4 or 8 by 50, you can use 2
and you get 4:25 as your answer
So it is A.
Answer:
<em>-3 = log₆(1/216)</em>
Step-by-step explanation:
Remember that when writing logarithm, the answer is:
exponent<em> = log</em>(base in subscript)y
also note that in exponential form, it looks like: y = b^x
Change
y = b^x = "(1/216) = 6^-3"
<em>-3 = log₆(1/216)</em>
<em>-3 = log₆(1/216) </em>is your answer
Answer:
it would be B.
Step-by-step explanation:
they would have gained 3 yards but then with the next play they would lose 7 yards leaving them with a total of -4 yards
