In 1993, Moose Population: 3280
In 1999, population became: 4960
P (Population) , t (years)
t = 6 —> 4960 - 3280 = 1680
Average Change —> 1680/6 = 280 moose/year
• In terms of 1990:
t = 3 —> 3280-3 (280)
P(1990) = 2440
P(t) = 2440 + 280t
• In 2003; t = 13
P(13) = 2440 + 280 (13)
P(13) = 2440 + 3640
P(13) = 6080
• Moose population in 2003
= 6080
Answer:
a) (0.124, 0.435)
b) I am 95% confident that the proportion difference is between 0.124 and 0.435
Step-by-step explanation:
Given that:
For male students: number of male students () = 69, number who liked the new method (x) = 38
For female students: number of female students () = 73, number who liked the new method (x) = 20
a) The probability that a male student like the new method () is given as:
The probability that a female student like the new method () is given as:
c = 95%, α = 1 -c = 0.05
the difference between the proportions of male and female students who like the new method better = ±
=
±
= (0.124, 0.435)
b) I am 95% confident that the proportion difference is between 0.124 and 0.435
