I am in the middle of the test rn... so if you know the answer could you please help me? Thx
First we need to write the null and alternate hypothesis for this case.
Let x be the average number of text message sent. Then
Null hypothesis: x = 100
Alternate hypothesis: x > 100
The p value is 0.0853
If p value > significance level, then the null hypothesis is not rejected. If p value < significance level, then the null hypothesis is rejected.
If significance level is 10%(0.10), the p value will be less than 0.10 and we reject the null hypothesis and CAN conclude that:
The mean number of text messages sent yesterday was greater than 100.
If significance level is 5%(0.05), the p value will be greater than 0.05 and we cannot reject the null hypothesis and CANNOT conclude that:
The mean number of text messages sent yesterday was greater than 100.
2 ¾= 11/4 Fraction. greater than 1 is 5/4.So, two 5/4 fits in 11/4. So, answer is 2.
Answer:
27Pi units squared
Step-by-step explanation:
step 1
Find the area of complete circle L
The area of circle is given by
we have
substitute
step 2
Find the area of the shaded sector
we know that
The area of complete circle subtends a central angle of 360 degrees
so
using proportion
Find out the area of sector by a central angle of 120 degrees
