A container holds 8 quarts of lemonade. How much is this in gallons?

Charra [1.4K]

$\text{The expression is representing the cost of a hamburger}\\\\\text{We know that from the question that the cost of a pizza slice}\\\text{is represented as "p", and the hamburger costs 3 more dollars}\\\text{than a pizza slice.}\\\\\text{So you're adding 3 dollars to the cost of the pizza to get the cost of a}\\ \text{hamburger}\\\\\text{Therefore, (p+3) = cost of hamburger}$

Using a sequencing method called "RNAseq," a researcher determines the level of FOXP2 expression

Wewaii [24]

The Z-score is 2.306 to three decimal places. However, the Z-test statistic value shows that it is greater than the Z-critical value, so we reject the null hypothesis $\mathbf{H_o}$

<h3>What is the Z-score of a test statistic?</h3>

A z-score is a measurement of how often standard deviations the score obtained from a z-test is beyond or under the mean population.

From the given data information, let us find the mean and the standard deviation.

$\mathbf{Mean (\bar x) = \dfrac{1154+5998+1007+...3987+4187+887}{10}}$

$\mathbf{Mean (\bar x) = \dfrac{24256}{10}}$

Mean (x) = 2425.6

The hypothesis testing can be computed as:

$\mathbf{H_o: \mu = 2425.6}$

$\mathbf{H_1: \mu \ne 2425.6}$

The standard deviation (σ) is:

$\mathbf{=\mathbf{ \sqrt{\dfrac{(1154-2425.6)^2+....+(887-2425.6)^2}{10-1}}}}$

$\mathbf{= \sqrt{3199489}}$

= 1788.71

Now, the Z-test statistic is determined using the formula:

$\mathbf{|Z| = |\dfrac{\bar x - \mu }{\sigma}| }$

$\mathbf{|Z| = |\dfrac{2425.6 -6550 }{1788.71}| }$

$\mathbf{|Z| = |-2.3058| }$

Z ≅ 2.306

Therefore, at a 0.05 level of significance, the Z-critical value is 2.306. However, since the Z-test statistic value shows that it is greater than the Z-critical value, so we reject the null hypothesis $\mathbf{H_o}$

The complete question is given as:

Using a sequencing method called "RNAseq," a researcher determines the level of FOXP2 expression in 10 different samples of lung tissue, and obtains these data:

1154 5998 1007 2501 1000 988 2547 3987 4187 887

Scientist has previously determined that FOXP2 is expressed in brain tissue at a level of 6,550. Calculate the Z-score associated with a test to see if the average expression of FOXP in her lung tissue samples is different from the levels she measured from brain tissue.

storchak [24]

Answer:

Step-by-step explanation:

Given that researchers wondered whether the size of a person's brain was related to the individual's mental capacity

They selected a sample of 5 females and 5 males and measured their MRI counts and IQ scores.

The data is reported to the right. Complete parts (a) through (d) below.

We want scatter plot for IQ vs MRI in general.

So we group data into two columns X for MRI and Y for IQ and draw scatter plot

MRI IQ

816932 133

1001121 140

833868 132

856472 140

866662 130

1038436 139

1079550 141

924059 136

a) Scatter plot is attached as a file

b) correlation coefficient = Cov (x,y)/S_x S_y = 0.729889

B) Yes, MRI count and IQ are linearly related since the linear correlation coefficient is _____.0.729889 >0.5 and near to 1 than to 0

There is a positive moderate correlation between x and y (linear)

Carly and Carter are comparing bedrooms. They are each getting new carpet and are trying to figure out which room will be the mo

Softa [21]

Answer:

Carter's bedroom would cost more to carpet than Carly's because the floor area of the former is about five square feet greater than the floor area of Carly's bedroom.

Step-by-step explanation:

The area of either of these floors is found by multiplying length by width:

A = L*W.

Carly's bedroom is 15.3 ft by 8.7 ft; multiplying, we get A = 133.11 ft^2

Carter's is 14.4 ft by 9.6 ft: A = 138.24 ft^2

Carter's bedroom area (138.24 ft^2) is about 5 ft^2 larger than Carly's and would thus cost more to carpet.
