A consumer testing service tested whether the average baking time of whole wheat bread in gas ovens was less than the average ba

Ten loaves of whole wheat bread were prepared and five were randomly assigned to be baked in the five randomly selected gas ovens and five were randomly assigned to be baked in the five randomly selected electric ovens.2.

Answer:

Part 1) The explanatory variable is the type of oven

It is a categorical variable

Part 2) The response variable is the baking time

It is a quantitative variable

part 3) two-sample z-test for proportions should be used for the test

Step-by-step explanation:

An explanatory variable is an independent variable that is not affected by all other variables. In this experiment, the type of oven is the input variable and it  is not affected by any other variable

A categorical variable is one that has two or more categories without any intrinsic ordering of the categories. The type of oven is either gas or electric, so it is categorical.

A response variable is a dependent variable whose variation depends on other variables. The baking time in this experiment depends on the type of oven used

A quantitative variable is one that take on numerical values.

A two proportion z-test allows you to compare two proportions to see if they are the same. The null hypothesis (H0) for the test is that the proportions are the same. The alternate hypothesis (H1) is that the proportions are not the same.

I need to find the median ,mean,mode,range,and
Makovka662 [10]
Median: 23.5
12 and 35 are in the middle so you add them and divide by 2, leaving you 
23.5 as your median.
Mean: 41.3
Add all numbers together and divide the sum by the number of numbers added. So all numbers added together equals 413. Divide by ten the nuber of numbers added. 413/10 equals 41.3. 
Mode: 99
The number that appears most often. In this case, 99 would be the mode. 
Range: 98
The lowest number subtracted from the highest number. 99-1 equals 98.
IQR: 84.75

Hope this helped! :)

(1/3)9 to the third power =
AlekseyPX
The answer would be 
1/3 * 9 = 3,
3^3 = 3*3*3, which then we multiply:
3*3=9, 9*3=27.
27 is the answer.


Hope this helps and have a nice day:)

50 1/2 divided by 1/4 = 202<br> How are the numbers related?
Stels [109]

Answer:

see the explanation

Step-by-step explanation:

Let

x=50\frac{1}{2}=\frac{50*2+1}{2}=\frac{101}{2}

y=\frac{1}{4}

Find the ratio x/y

\frac{x}{y}=\frac{(101/2)}{(1/4)} =\frac{101*4}{2*1}=202

therefore

\frac{x}{y}=202

x=202y

That means----> The first number (50 1/2) is 202 times greater than the second number (1/4)
