Answer:
Given : PQR is a triangle.
Such that,
Prove:
Construct median PM.
⇒M is the mid point of line segment QR ( by the definition of median )
Therefore, (By the definition of mid point)
(given)
( reflexive)
Thus, By SSS congruence postulate,
Thus, BY CPCTC,
Hence proved.
Answer:
: P=0.60
: P>0.60
Step-by-step explanation:
Hypothesis test requires to state a null hypothesis and an alternative hypothesis. The hypotheses are stated in such a way that they are mutually exclusive. That is, if one is true, the other must be false; and vice versa. Then sample data will be used to accept or reject the null hypothesis in a given significance level.
Let P be the true proportion of customers that are carrying two Wi-Fi devices.
We can state the null and alternative hypothesis as follows:
: P=0.60
: P>0.60
Before conducting the test, we need to check if n×0.06≥10
Since n=78 this condition holds, therefore we can apply the hypothesis test.
