Answer:
yes
Step-by-step explanation:
Answer:
h ≈ 13.4
Step-by-step explanation:
Since the triangle is right we can use the sine ratio to find h
sin48° =
= 
Multiply both sides by 18
18 × sin48° = h
⇒ h = 13.4 cm ( to 1 dec. place )
Answer:
--- test statistic
--- p value
Conclusion: Fail to reject the null hypothesis.
Step-by-step explanation:
Given


--- Null hypothesis
---- Alternate hypothesis

Solving (a): The test statistic
This is calculated as:

So, we have:






Solving (b): The p value
This is calculated as:

So, we have:

Look up the z probability in the z score table. So, the expression becomes


Solving (c): With
, what is the conclusion based on the p value
We have:

In (b), we have:

By comparison:

i.e.

So, we fail to reject the null hypothesis.
Interest on the amount is Rs 2000.
Step-by-step explanation:
- Step 1: Given principal amount = Rs 4000 and amount = Rs 6000
- Step 2: Formula for Amount, A = Principal, P + Interest, I
⇒ 6000 = 4000 + I
⇒ I = 6000 - 4000 = Rs 2000
