Answer:
The number of people vote for blue is 180.
Step-by-step explanation:
Let there are x numbers of total people.
So, 
of total people vote for blue i.e. 
people vote for blue.
Now, the remaining number of people are 
.
If 
of the remaining people vote for green, then the number of people vote for green will be 
.
Therefore, finally the remaining number of people is 
and they vote for red.
Now, 
{Given}
⇒ x = 288
And the number of people vote for blue is 
. (Answer)
Answer:
9/4
Step-by-step explanation:
9 out of 4 are blue, just flip the ratio.
Complete question :
A data set includes data from student evaluations of courses. The summary statistics are nequals92, x overbarequals4.09, sequals0.55. Use a 0.10 significance level to test the claim that the population of student course evaluations has a mean equal to 4.25. Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim.
Answer:
H0 : μ = 4.25
H1 : μ < 4.25
T = - 2.79
Pvalue =0.0026354
we conclude that there is enough evidence to conclude that population mean is different from 4.25 at 10%
Step-by-step explanation:
Given :
n = 92, xbar = 4.09, s = 0.55 ; μ = 4.25
H0 : μ = 4.25
H1 : μ < 4.25
The test statistic :
T = (xbar - μ) ÷ s / √n
T = (4.09 - 4.25) ÷ 0.55/√92
T = - 0.16 / 0.0573414
T = - 2.79
The Pvalue can be obtained from the test statistic, using the Pvalue calculator
Pvalue : (Z < - 2.79) = 0.0026354
Pvalue < α ; Hence, we reject the Null
Thus, we conclude that there is enough evidence to conclude that population mean is different from 4.25 at 10%
