Answer:
Option 4 - The expression is equivalent to 12 + 3 + (-7) because of the commutative property.
Step-by-step explanation:
To find : Which statement is true about the expression ?
Solution :
Associative property states that,
Commutative property states that,
By definition of properties we conclude that option 4 applies the correct property i.e. commutative.
As
Therefore, The expression is equivalent to because of the commutative property.
So, Option 4 is correct.
Answer:
B
Step-by-step explanation:
- A 95% confidence level interval will have 0.52 (lower interval) & 0.68 (upper interval) which means that that if 90 individuals root for North HS then p value is 0.6 which will fall in the 95% confidence interval range.
- For the option B the p value will also be same as in case A hence B is true as an alternative hypothesis.
- We can calculate P value
Confidence Interval = p ± z
