Answer with explanation:</h2>
Let p be the population proportion .
Then, 
According to the given information, we have
, since alternative hypothesis is two-tailed , so the hypothesis test is a two-tail test.
Since sample size is large (n> 30), we use z-test.
Let us consider 95% confidence i.e.
.
c) Critical value = 
Sample proportion : 
d) Test statistic : 
i.e. 
e) P-value (for two-tail) : 
f) P-value is the probability value that we have falsely rejected the null hypothesis.
g) Since observed z-value (2.8) does not lie in critical interval (-1.96, 1.96), it means the null hypothesis is rejected.
Each class collected at least 54 cans...
54 * 29 = 1566....the least amount collected
Its a 90 degree right angle because of how two of the segments in the triangle are shaped like a perfect letter L
Answer: 10,985 students
Step-by-step explanation:
You are given the original number of students, the rate of growth and the number of years. The Future value formula can therefore be used:
Number of students in 2010 = Number of students in 1995 * ( 1 + growth rate) ^ number of years
Number of years = 2010 - 1995 = 15 years
Number of students in 2010 = 1,350 * ( 1 + 15%)¹⁵
= 10,985 students
