The value of the given expression will be equal to -3.
What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
The solution to the expression is:-
= 4( x + 3 ) ( x + 1 ) / ( x + 5 ) ( x - 5 )
= 4( 3 + 3 ) ( 3 + 1 ) / ( 3 + 5 ) ( 3 - 5 )
= ( 4 x 6 x 4 ) / ( 8 x -2 )
= -3
Therefore the value of the given expression will be equal to -3.

c) Repeat b), assuming the percentages are based on independant simple random samples of 1,000 first year college students drawn each year.
Answers
Answer:
a. The difference is important but the question does not make sense
b. Yes, it makes sense to ask if the difference is statistically significant.
c. Please check explanation
Step-by-step explanation:
From the question, we identify the following relation;
:
= 0
:
≠ 0
a) The difference is important as asked, but the cultural atmosphere difference of over 30 years makes the question somehow not making sense
b) Yes, it makes sense. In order to answer, it is necessary to know the sample size of the year 2000 survey.
We can answer the question on the basis of the information given.
c) We proceed here as follows;
α = 0.05 , = 1.96 ( This is the critical value)
Thus, z = (0.74-0.36)/√(0.36-0.64)/1000 = 25.03
We make the following conclusions; Since 25.03 > 1.96, the null hypothesis is rejected which means that the proportion of people who think being well officially is important has changed since 1970.
