Answer:
Given:
Sample size, n = 20
Significance level = 5% = 0.05
Mean, u = 8
Here, the sample mean was not given.
Here the null and alternative hypothesis will be:
H0 : u = 8
H1 : u < 8
In this case, since there is no evidence to reject the null hypothesis, H0, at 0.05 level of significance, we can say that the p-value is greater than the level of significance, 0.05.
Answer:
D 192
Step-by-step explanation:
used: new: total
4: 1 : 5
We have 240 stamps
240/5 = 48
Multiply each number by 48
used: new: total
4*48: 1*48 : 5*48
192 : 48 : 240
There are 192 used stamps and 48 new stamps in his collections
Three times the square of a number means
Nine times a number is
If these quantities must be equal, we have
We can divide both sides by 3 to get
Since x is non-zero, we can divide both sides by x:
