The null hypothesis is that there is no difference between the mean number of swallows taken to finish a drink among patrons experiencing the high-volume noise level of 88 dB and the mean number of swallows taken to finish a drink among those experiencing the normal rouse level of 72 dB. The alternative hypothesis is that there is a difference between the mean number of swallows taken to finish a drink among patrons experiencing the louder noise level of 88 dB and the mean number of swallow taken to finish a drink among those experiencing the normal noise level of 72 dB. Below are the graphs of two possible data sets. The horizontal axes display the number of swallows taken to finish a drink, while the vertical axes display the number of observed patrons who took that number of swallows to finish a drink. Use these graphs to answer the questions that follow. Which data set appears to have move variability between treatments that within treatments? Data set A Data set B The data that you collect suggest that the between-treatments variance is large, relative to the within treatment variance, so the F ratio for out study is likely to be suggesting that .

yor answer is 7/6 times 5

step-by-step explanation:

which expression can be used to convert 80 us dollars (usd) to australian dollars (aud)?

1 usd = 1.0343 aud

1 aud = 0.9668 usd

step-by-step explanation:

sorry just need the points

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
