The confidence interval for population mean is given by :-

Given : Sample size : n= 5, since n<30 , so the test we use here is t-test.
Sample mean : 
Standard deviation: 
Significance level : 
By using the standard normal distribution table , the critical value corresponds to the given significance level will be :-

Now, the 99% confidence interval for the mean waste recycled per person per day for the population of Texas will be :-

Hence, the 99% confidence interval for the mean waste recycled per person per day for the population of Texas = (0.068, 3.732)
Answer:
30° each
Step-by-step explanation:
Complementary angles are those that add up to 90° so if they are all equal then it's
90/3=30°
Answer:
mean is = 28.4
median is = 26
Step-by-step explanation:
mean- average
( 25+ 27+ 24+ 26+ 40 )/5 = 28.4
median- middle
25, 27, 24, 26, 40
{ rearrange }
24, 25, 26, 27, 40
the middle number is 26
I'm pretty sure that it's the first one: direct variation; y=4x.
