=-6/4
Step-by-step explanation:
You would do 300• 31/100 to get 90. I’m pretty sure that’s right
If you would like to write 0.097 in fractional notation, you can do this like this:
0.097 = 97 / 1000
The correct result would be <span>A 97/1000.</span>
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.
The worm would move 6.375 inches in 85 minutes (1 hour 25 minutes).
