Answer:
Step-by-step explanation:
<h3>Part A</h3>
<u>Given function:</u>
(1.03)ˣ in this function indicates the rate of increase. The increase is 1.03 times per year.
- 1.03 = 103% = 100% + 3%
- This is a 3% increase per year
<h3>Part B</h3>
<u>The increase rate is:</u>
- 10201/10100 = 1.01 times
- 1.01 = 101% = 100% + 1%
- This is a 1% increase per year
As we see the product A has greater percent change
Answer:
(a) State the appropriate null and alternative hypotheses to assess whether women are taller today.
Solution:
Definition of null hypothesis : The null hypothesis attempts to show that no variation exists between variables or that a single variable is no different than its mean. it is denoted
Alternative Hypothesis: In statistical hypothesis testing, the alternative hypothesis is a position that states something is happening, a new theory is true instead of an old one (null hypothesis).
We are given that The mean height of women 20 years of age or older was 63.7 inches.
So, null hypothesis :
Alternative Hypothesis :
b)The P-value for this test is 0.16.
Solution: The p-value represents the probability of getting a sample mean height of 65.1 inches.
c) Write a conclusion for this hypothesis test assuming an alpha equals 0.10 level of significance.
Solution:
p- value = 0.16
Since the p - value is high .
So, we will accept the null hypothesis
So,
Hence The mean height is 63.7 inches
Answer:
sq root of 58
Step-by-step explanation:
No it isn't.
Explanation:
x/y * y = (y-6) * y
x = y^2 - 6y
A function gives just one y for every x
In this case there will always be 2 y's for every x
Example:
y can be
y = 6
or
y =−6
(0,-6) & (0,6)
