Answer:
Null hypothesis is; H0: μ = 174.1 cm
Alternative hypothesis is; Ha: μ ≠ 174.1 cm
No, it's not possible to conclude that there is enough evidence to support the claim.
Step-by-step explanation:
We are told that the A formal hypothesis test is to be conducted using the claim that the mean height of men is equal to 174.1 cm.
This means that the null hypothesis is;
H0: μ = 174.1 cm
Now, the alternative hypothesis would state the opposite of the null hypothesis. Thus, alternative hypothesis is;
Ha: μ ≠ 174.1 cm
The possible conclusions to make is that we can either reject the null hypothesis or fail to reject the null hypothesis.
Since we don't have value of test statistic and degree of significance, we cannot conclude that "there is sufficient evidence to support the claim that the mean height of men is equal to 174.1 cm"
Answer:
y=0.5x-3.5
Step-by-step explanation:
(-4)-(-5)=1
3-1=2
1/2=0.5
y=0.5x-3.5
Answer:
5
Step-by-step explanation:
Using the rule of radicals
× ⇔ , then
=
= × = 5
Now, she writes 4 notes every 1 hour.
so in 2 hours she has written 8 notes, and the remaining is 50 - 8 or 42.
in 3 hours has written 12 notes, and remaining are 50 - 12, or 38, and so on.
now, how many hours will it take her to them all? or, how many times does 4 go into 50? 50 /4 or 12.5.
so it will take her 12 hours and a half to do them all, at that time, the remaining notes are 0, because she's done, and the hours are 12 and a half.
Answer:
-3 < x ≤ 8
Step-by-step explanation:
First, write this statement with symbols:
2x - 5 > -3, but also:
2x - 5 ≤ 11
Adding 5 to both sides of the first inequality yields 2x > 2. pr x > 1.
Adding 5 to both sides of the second inequality results in 2x ≤ 16, or x ≤ 8.
Thus, -3 < x ≤ 8 is the shortest way in which to write the given information.
