A magazine presented a lesson in hypothesis testing carried out by medical students in a biostatistics class. Students were​ bli

nd-folded and then given a​ red-colored or​ yellow-colored gummy bear to chew.​ (Half the students were randomly assigned to receive the red gummy bear and half to receive the yellow bear. The students could not see what color gummy bear they were​ given.) After​ chewing, the students were asked to guess the color of the candy based on the flavor. Of the 123 students who participated in the​ study, 70 correctly identified the color of the gummy bear.
If there is no relationship between color and gummy bear flavor, what proportion of the population of students will correctly identify the color?

Answer:

p = 0.5

Step-by-step explanation:

in order to determine what proportion of the population of students will correctly identify the color

given that

n  = 123

x = 70

sample proportion P = X/N =  70/123

P = 0.569

Find the output, y, when the input, x, is 666.
nata0808 [166]

Answer:

y = 8

Step-by-step explanation:

The question is simply asking for the y-value when x = 6. We look at the graph when x = 6 and see what y-value it gives us. We find that when x = 6, we have y = 8.

what is remainder theorem ? explain how to use remainder thereom and factor theorem for linear polynomial .
elena55 [62]
Basically the Remainder theorem states  that the remainder of dividing a polynomial P(x) by (x - a) is given by P(a).

So for example if we divide  x^ 2 - 2x + 7  by x - 2  the remainder  will be 
2^2 - 2(2) + 7  =  7.. 

If the remainder is 0 then the divisor will be a factor of the polynomial.  This is the Factor Theorem and can be used to test if a given polynomial has a factor  x-a.

What is the value of 36X negative Y over to when X equals three and Y equals -6
Rus_ich [418]

<u><em>Note:</em></u>

<em>Your question is a little unclear. But, from my understanding, I assume you may be asking the evaluation of the expression 36x - y when x = 3 and y = -6.</em>

<em>so I will solve based on my assumption which anyways would clear your concept.</em>

Answer:

The value of 36x - y when x = 3 and y = -6 will be: 114

Step-by-step explanation:

Given

Assuming the expression

36x - y

To Determine

Evaluate 36x - y when x = 3 and y = -6

Given the expression

36x - y

substitute x = 3 and y = -6 to evaluate the expression

36x-y= 36(3) - (-6)

            = 108+6

            = 114

Therefore, the value of 36x - y when x = 3 and y = -6 will be: 114

The cost for hiring a car for 2 days in 2018 was Rs. 264 which was 20% more than in 2013. What was the cost of hiring a car for
Goshia [24]

The cost of hiring a car for 2 days in 2013 is Rs. 316.8

<h3>How to find the cost of hiring in 2013 ?</h3>

The cost for hiring a car for 2 days in 2018 was Rs. 264 which was 20% more than in 2013.

Therefore,

cost of hiring for 2018 = Rs. 264

Therefore,

let

cost of hiring in 2013 = 20%(264) + 264

cost of hiring in 2013 = 20 / 100 × 264 + 264

cost of hiring in 2013 = 1 / 5 × 264 + 264

cost of hiring in 2013 = 264 / 5 + 264

cost of hiring in 2013 = 52.8 + 264

cost of hiring in 2013 = 316.8

Therefore, the cost of hiring a car for 2 days in 2013 is Rs. 316.8.
