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:
2 is -1/3
3 is -6
4 is 2
Step-by-step explanation:
2 is 7x + 8x = 3x - 4
3 is 5x + (-3) = 2x + (-15)
4 is -4x + 17 = 6x -3
Answer: She's used 630 minutes.
Step-by-step explanation:
She has 1400 minutes.
She used 45% of them.
1. Convert 45% to decimals. You can do by dividing by 100.
![\frac{45}{100}=0.45](https://tex.z-dn.net/?f=%5Cfrac%7B45%7D%7B100%7D%3D0.45)
2. Multiply by the total amount of minutes.
![0.45(1400)=630](https://tex.z-dn.net/?f=0.45%281400%29%3D630)
Answer:
f(96) = 85
Step-by-step explanation:
f'(95) gives us the slop of 6, which can be used to estimate the increase
of the next number.
Ex) f(95) = 79 & f'(95) = 6 so
f(96) = 79 + 6 = 85
