I think this is the answer
SOLUTION:
Case: Hypothesis testing
Step 1: Null and Alternative hypotheses

Step 2: T-test analysis

Step 3: t-test with the significance level

Step 4: Comparing

So tail to reject the null hypothesis. There is enough evidence at a 0.05 level of significance to claim that the mean spent is greater than P127.50.
Final answer:
Yes, there is evidence sufficient to conclude that the mean amount spent is greater than P127.50 per month at a 0.05 level of significance.
2 + 6 = 8. 2 is left. 6 is left.
Answer:

Step-by-step explanation:
We need to find which statements are true.
Solution to find the same we will solve each statement and will conclude the same.
1. 
Now On solving we get;


So we can see that 0.70 > 0.66
Hence The given statement is False.
2. 
Now On solving we get;


So we can see that 0.5625 > 0.5
Hence The given statement is True.
3. 
Now On solving we get;


So we can see that 1.33 > 1.2
Hence The given statement is False.
4. 
Now On solving we get;


So we can see that 0.82 > 0.66
Hence The given statement is False.
Answer:
i belive the answer should be x = 0
Step-by-step explanation:
Since two opposites add up to zero, remove them from the expression
and then 7=1 the statement is false for any value of x
