Samsung is trying to decide whether to produce an upgrade of one of its cell phone software. Customers would have to pay $95 for the upgrade. For the upgrade to be profitable, the company must sell it to more than 25% of their customers. The company will survey a random sample of 50 customers about this issue Which would be a more serious mistake in this setting—a Type I error or a Type II error? Justify your answer.
In the company's survey, 14 customers are willing to pay $95 each for the upgrade. Do the sample data give convincing evidence that more than 25% of the company’s customers are willing to purchase the upgrade? Carry out an appropriate test at the α=0.05 significance level.

is there  a multiple question?

Step-by-step explanation:

=====================================

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
