likoan [24]

Answer:

This is an example of placebo testing.

Step-by-step explanation:

This is an example of placebo testing in which, the two groups are given two substances that are said to have an effect on the condition that is being treated but one of them is the actual medicine that is being tested while the other one has no real effect over the medical condition. But the volunteers are not given information on which of the medicines is real and which is not, so that this does not affect the outcome of the experiment.

I hope this answer helps.

A fair six-sided die, with sides numbered 1 through 6, will be rolled a total of 15 times. Let x¯1 represent the average of the
Anna35 [415]

Answer:

option B

Step-by-step explanation:

P(x =x) [{\frac{1}{6} ;x =1,2,3...6]

E (x) = \frac{6+1}{2} =\frac{7}{2} =3.5\\\\E(x)=3.5

Given random experiment of tossing of 6 sided dice is follow above distribution

Therefore, suppose x₁, x₂ ...x₁₀ are 10 independent and indentical random variable which represent first 10 rolls

Average of first 10 rows equals

\bar x_1 =\frac{ \sum ^{10}_{i=1}xi}{10}

E(\bar x_1)=\frac{ \sum ^{10}_{i=1}E(x_1)}{10} \\\\=\frac{10(3.5)}{10} \\\\=3.5\\\\E(\bar x_1) = 3.5----(1)

now suppose ,

x₁₁,x₁₂, ...x₁₅ are 5 independent and identical random variable which represent last 5 roll

average of last 5 roll is

E(\bar x_2)= \frac{ \sum ^{5}_{i=1}xi}{5} \\\\= \frac{5 \times(3.5)}{5} \\\\=3.5

Therefore,\bar x_1 - \bar x_2

3.5 - 3.5 = 0

Nicholas borrowed $250 from his parents to buy a video game system. He has agreed to pay them back $15 each week. Which equation
AfilCa [17]

Answer:

p = 250 - 15(w)

Step-by-step explanation:

Original amount: 250

No of weeks to return money:  w

Amount to pay each week: 15  

Amount that he has paid back: 15 × w  (When we subtract this term from the total we will get the answer)

So after w weeks he owes his parents :

p = 250 - 15(w)
