Answer:
Given the information in the question;
a) The parameter of interest is the population of artists who are left-handed and its is 10% = (10/1000 = 0.10
b) The Null hypothesis and alternative hypothesis are;
<em>H₀ : p </em>= 0.10
<em>H₁ : p</em> > 0.10
c) The sample proportion is calculated as:
p = number of left handed artist / sample size
p = 26 / 200
p = 0.13
d) To find the p-value, The researcher should calculate the probability that the sample proportion would be 0.13 or larger for a sample of size 200 if the population proportion is actually 0.10.
Lets look at the info we have:-
400 personal video players and find that 399 have NO defects.
Solve:-
2000 ÷ 400 = 5
So, about 5 of the video players will be defect.
