Answer:

**Answer:**

A

**Step-by-step explanation:**

P^T is transpote matrix. So the rows of matrix P you write like columns in P^T.

So we have first row: 2, 5, it will be firsl column

2nd row: 8,1 will be 2nd column.

It is matrix:

2 8

5 1

This is matrix a)

Find the range, variance, and standard deviation for the given sample data. Include appropriate units in the results.Listed below are the measured radiation absorption rates (in W/kg) corresponding to various cell phone models. If one of each model is measured for radiation and the results are used to find the measures of variation, are the results typical of the population of cell phones that are in use?0.950.950.730.730.630.630.910.911.321.321.481.480.630.631.231.230.910.911.411.41 0.670.67The range of the sample data isnothing▼(Round to three decimal places as needed.)Sample standarddeviationequals=nothing▼kg.kg.left parenthesis Upper W divided by kg right parenthesis squared .W/kg2.W.W.Upper W divided by kg.W/kg.(Round to three decimal places as needed.)Samplevarianceequals=nothing▼kg.kg.left parenthesis Upper W divided by kg right parenthesis squared .W/kg2.Upper W divided by kg.W/kg.W.W.(Round to three decimal places as needed.)If one of each model is measured for radiation and the results are used to find the measures of variation, are the results typical of the population of cell phones that are in use?A. No, because it is necessary to have at least 5 of each cell phone in order to get a meaningful result. Only including one of each cell phone model is not representative of each cell phone model.B. Yes, because the results from any sample of cell phones will be typical of the population.C. Yes, because each model is being represented in the sample. Any sample that considers all possible cell phone models will produce results typical of the population of cell phones.D. No, because some models of cell phones will have a larger market share than others. Measures from different models should be weighted according to their size in the population.

**Answer:**

WHERE IS THE TABLES HM???

**Answer:**

**a) **0.2119 = 21.19% probability that the average percent of fat calories consumed is more than thirty-seven.

**b) **The first quartile for the average percent of fat calories is 33.31

**Step-by-step explanation:**

To solve this question, we have to understand the normal probability distribution and the central limit theorem.

**Normal probability distribution:**

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean and standard deviation , the zscore of a measure X is given by:

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.

**Central limit theorem:**

The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , a large sample size can be approximated to a normal distribution with mean and standard deviation

**In this problem, we have that:**

**(a) For the group of 16 individuals, find the probability that the average percent of fat calories consumed is more than thirty-seven. (Round your answer to four decimal places.) **

This is the 1 subtracted by the pvalue of Z when X = 37. So

By the Central Limit Theorem

has a pvalue of 0.7881

1 - 0.7881 = 0.2119

0.2119 = 21.19% probability that the average percent of fat calories consumed is more than thirty-seven.

**b) Find the first quartile for the average percent of fat calories. (Round your answer to two decimal places.) percent of fat calories**

The 1st quartile is the 25th percentile. So this is the value of X when Z has a pvalue of 0.25. So it is X when Z = -0.675. So

The first quartile for the average percent of fat calories is 33.31

**Answer:**

The cell wall lies outside the plasma membrane. The plant cell wall is mainly composed of cellulose. Cellulose is a complex substance and provides structural strength to plants. Bacteria is not a plant therefore its cell wall is made up of peptidoglycan

** - Classmate**

**Answer: f(3)=10**

**Step-by-step explanation:**

In order to calculate f(3) you need to substitute 3 for x in function

f(x)=3x +1 :

f(3)=( 3x3) + 1

f(3)= 9+1

f(3)=10
