Answer:
a. True
Step-by-step explanation:
By ∝= 5% we mean that there are about 5 chances in 100 of incorrectly rejecting a true null hypothesis. To put it in another way , we say that we are 95% confident in making the correct decision.
In the given question the null hypothesis is
H0: u ≤ 1 hour and Ha: u > 1 hour
So there is a 5% chance that the erroneous conclusion will be made that students spend on average more than 1 hour per assignment.
The given statement is true.

Answer:
Can' possible......
Step-by-step explanation:
Let suppose the numbers are:
x
x + 1
x + 2
Now according to given condition:
x + x +1 + x+ 2 = -206
By adding we get:
3x + 3 = -206 Subtracting 3 from both sides:
3x + 3 - 3 = -206 -3
Both terms on right side have negative sign so we will add them. (answer will have negative sign.)
3x = -209
Dividing both sides by 3:
x = -209/3
x = -69.6666
that is not an integer so the question is wrong.
I hope it will help you!
