Answer:
P(Spinner lands on purple section) = 0.6 = 60%
Step-by-step explanation:
We are given the following in the question:
Number of sections = 10
Number of purple sections = 6
a) probability that the spinner will land on purple purple
P(purple) =
0.6 is the probability that the spinner will land on purple purple.
b) Interpretation of probability
There is a 60% chance that the spinner will land on purple color.
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.
