A research study examined the blood vitamin D levels of the entire US population of landscape gardeners. The population average level of vitamin D in US landscapers was found to be 30.8 ng/mL with a standard deviation of 4.371 ng/mL. Assuming the true distribution of blood vitamin D levels follows a normal distribution, if you randomly select a landscaper in the US, what is the likelihood that his/her vitamin D level will be between 36.84 and 39.73 ng/mL
Answers
Answer:
0.0631 = 6.31% probability that his/her vitamin D level will be between 36.84 and 39.73 ng/mL
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score 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 p-value, we get the probability that the value of the measure is greater than X.
The population average level of vitamin D in US landscapers was found to be 30.8 ng/mL with a standard deviation of 4.371 ng/mL
This means that [tex]\mu = 30.8, \sigma = 4.371[/tex]
What is the likelihood that his/her vitamin D level will be between 36.84 and 39.73 ng/mL?
This is the pvalue of Z when X = 39.73 subtracted by the pvalue of Z when X = 36.84.
X = 39.73
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{39.73 - 30.8}{4.371}[/tex]
[tex]Z = 2.04[/tex]
[tex]Z = 2.04[/tex] has a pvalue of 0.9793
X = 36.84
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{36.84 - 30.8}{4.371}[/tex]
[tex]Z = 1.38[/tex]
[tex]Z = 1.38[/tex] has a pvalue of 0.9162
0.9793 - 0.9162 = 0.0631
0.0631 = 6.31% probability that his/her vitamin D level will be between 36.84 and 39.73 ng/mL

What is the better deal? 6 for $6.99 or 24 for $13.99
Answers
13.99/24=.58
Therefore better to buy more as the unit price per item is cheaper
Answer:
24 for $13.99
Step-by-step explanation:
Find the cost of 1 for both deals.
6 for $6.99. Divide 6.99 with 6:
6.99/6 = 1.165
~$1.17 for one.
24 for $13.99. Divide 13.99 with 24:
13.99/24 = ~0.582
~$0.58 for one.
24 for $13.99 is the better deal, by ~59¢.

An object travels along a horizontal straight path at a constant rate. The object travels 1/2 of the
length of the path in 3/4 second. At that rate, how many seconds does it take the object to travel the
entire length of the path?
Answers
Answer:
1.5 seconds
Step-by-step explanation:
Given that,
The object travels 1/2 of the length of the path in 3/4 second.
We need to find the time it takes the object to travel the entire length of the path.
1/2 of length = 3/4 seconds
Entire length,
[tex]=\dfrac{3}{4}\times 2\\\\=1.5\ s[/tex]
So, it will take 1.5 seconds to cover the entire length of the path.

What are fit equations?Fitting an equation to data is finding a linear, quadratic, exponential, or any other sort of function whose graph includes, or comes as close as possible to, a given set of data in the form of ordered pairs. The relative predictive power of a model shows how accurately the model is related to the data.
The theoretical pattern best accounts for the relationships among variables in a data set. For example, a regression equation having the best fit to sample data is the one that minimizes differences between observed and predicted values.
