ats in a box with colorful wallpaper. The average rat (of this strain) can learn to run this type of maze in a box without any special coloring in an average of 25 trials, with a variance of 64, and a normal distribution. The mean number of trials to learn the maze, for the rats tested with the colorful wallpaper, is 11.What is the μM ?• A. 8• B. 11• C. 25• D. 64

Answer:  C. 25

Step-by-step explanation:

Given : The average rat (of this strain) can learn to run this type of maze in a box without any special coloring : \mu=25

The mean number of trials to learn the maze, for the rats tested with the colorful wallpaper= M= 11

We know that the sampling distribution D is given by :-

\mu_D=\mu

Similarly the mean of the distribution M in the given situation is given by :_

\mu_M=\mu=25

Which equation represents a line that passes through (4, left-parenthesis 4, StartFraction one-third EndFraction right-parenthes
Alina [70]

Answer:

y-\frac{1}{3}=\frac{3}{4}(x-4)

Step-by-step explanation:

we know that

The equation of the line into point slope form is equal to

y-y1=m(x-x1)

In this problem we have

point\ (4,\frac{1}{3})

m=\frac{3}{4}

substitute the given values

y-\frac{1}{3}=\frac{3}{4}(x-4)

y minus StartFraction one-third EndFraction equals StartFraction 3 Over 4 EndFraction left-parenthesis x minus 4 right-parenthesis.(x – 4)

In the context of relationships between variables, increases in the values of one variable are accompanied by increases in the v
TiliK225 [7]

Answer: Directly proportional.

Step-by-step explanation:

The increase of one variable which causes the other variable to increase points to a directly proportional relationship between the two variables. Similarly, the decrease of one variable will cause a decrease in the other variable.

One variable can also be the constant multiple of the other. This means that if one changes, the other one will change in PROPORTION to it.

Answer:

draw a number line from 66 to 81

make your minimum 67

lower quartile should be on 70

the median on 77

upper quartile and maximum on 80

(note that your upper quartile and maximum is both on 80 so there won't be an extension as you normally would see on a box plot)

You can search up "box plot" and go on images to see what i mean

(copy and pasted from your last post!)

Step-by-step explanation:

I can probably help on part 4 and send a sketch but I currently can't use my phone to send a pic and I am currently on my desktop :'(
