Answer:
As the average has increased the height of the new player must be more then the height of the player which was injured.
The difference between the previous average and the new average is 0.01 m.
Therefore the average is increased by 0.01 m.
Therefore the total height of all the players is increased by 0.01*11=0.11 m
Therefore as the increase in the total height is made by the player with height 1.85 m,the height of the player who was injured is 1.85–0.11=1.74 m
The height of the player who was injured is 1.74 m
Step-by-step explanation:
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.
