Answer:
Given:
mean, u = 6.2
sample size, n = 180
Sample mean, X' = 6.3
s.d = 0.9
Significance level = 0.05
The null and alternative hypothesis will be:
H0 : u = 6.2
H1 : u > 6.2
Degree of freedom = 180 - 1 = 179
Using t table, the t critical value,
t> t(0.05, 179) = 1.6534
The test statistic:
Since the test statistic(t calculated value) 1.4907 < t critical value (1.6534), we fail to reject the null hypothesis H0.
Answer:
Step-by-step explanation:
From the given figure it is clear that we two rays because both sides have one endpoint and goes on infinitely in only one direction.
If a ray has end point at A and goes on infinitely in only one direction towards point B, then ray is denoted as .
For first side, we have point V as end point and ray goes goes on infinitely in only one direction towards point U. So, first side is .
For second side, we have point V as end point and ray goes goes on infinitely in only one direction towards point W. So, second side is .
Therefore, the sides are .
