A study suggested that childrenbetween the ages of 6 and 11 in the US have anaverage weightof 74 lbs. with a standard deviation of 2.7 lbs.If we assumethe weights are normally distributed, what proportion of childrenin this age range between 70 lbs. and 85 lbs.
Answer:
The proportion of children in this age range between 70 lbs and 85 lbs is of 0.9306.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
A study suggested that children between the ages of 6 and 11 in the US have an average weightof 74 lbs, with a standard deviation of 2.7 lbs.
This means that [tex]\mu = 74, \sigma = 2.7[/tex]
What proportion of childrenin this age range between 70 lbs and 85 lbs.
This is the pvalue of Z when X = 85 subtracted by the pvalue of Z when X = 70. So
X = 85
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{85 - 74}{2.7}[/tex]
[tex]Z = 4.07[/tex]
[tex]Z = 4.07[/tex] has a pvalue of 1
X = 70
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{70 - 74}{2.7}[/tex]
[tex]Z = -1.48[/tex]
[tex]Z = -1.48[/tex] has a pvalue of 0.0694
1 - 0.0694 = 0.9306
The proportion of children in this age range between 70 lbs and 85 lbs is of 0.9306.
How many degrees is angle x?
Answer:
Step-by-step explanation:
acute angle
Answer:
40 degrees
Step-by-step explanation:
The way I did this (and it won't make much sense I know but its just my way of doing it), is to subtract the bigger angle on the tool by the smaller angle. For example, like in the image, one arrow is at 120 degrees and another at 80 degrees, so I would just do 120-80 which equals 40, and because we talk about angles in the hood its 40 degrees, not plain 40

If you overestimate the standard deviation of the population, which type of error are you potentially increasing
Answer:
Standard Error
Step-by-step explanation:
The standard deviation is directly proportional to the sample standard deviation or standard error.
According to the relation :
Standard Error = standard deviation / sqrt(sample size)
Going by these relation an increase in the value of standard deviation will favor or increase the standard error withba constant Number of samples.
Therefore, overestimating the standard deviation will. Cause an increase in the standard error, while underestimating the standard deviation will also lower the standard error.

NEED THIS ASAP
NEED A EXAM DONE WILL PAY
Answer:
f5= 5
Step-by-step explanation:
The value of F₅ in the given Fibonacci sequence is 5, i.e. option A is the correct answer.
What is the Fibonacci sequence?Fibonacci sequence is a sequence in which each number is the sum of the two preceding ones.
i.e.
[tex]F_n = F_{n-1} + F_{n-2}[/tex]
We have,
Fibonacci sequence {0, 1, 1, 2, 3, 5, 8, ...}
i.e.
F₁ = 0, F₁ = 1, F₂ = 1, F₃ = 2, F₄ = 3, F₅ = 5, F₆ = 8
Now,
We have to find the value of F₅,
Here, for n = 5,
i.e.
[tex]F_5 = F_{5-1} + F_{5-2}[/tex]
i.e.
F₅ = F₄ + F₃
So,
F₅ = 3 + 2
So,
We get,
F₅ = 5
So, the value of F₅ for the given sequence is F₅.
Hence, we can say that the value of F₅ in the given Fibonacci sequence is 5, i.e. option A is the correct answer.

What is the smallest possible value x could take given that it must be an integer?
x>−3
Answer:
The smallest possible value that x could take is -2.
Step-by-step explanation:
Integer values:
Integer values can be either positive or negative, with no decimal parts. The integer set is given by:
{...,-3,-2,-1,0,1,2,3,....}
x>−3
We want the first integer on the number line that is greater than -3. This is -2.
So the smallest possible value that x could take is -2.
