Answer:
16.5x = 465.3
Step-by-step explanation:
The distance traveled is equal to the gallons time the miles per gallon
465.3 = 16.5 * x where x is the miles per gallon
16.5x = 465.3
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%
Answer: 14
Step-by-step explanation:
13 + 6/6 = ?
13 + 1 = 14
Answer:
19/12 or 1/7/12
Step-by-step explanation:
- find what is common in both denominators. in this case 12 can be divisible.
- 3x3/4x3 + 5x2/6x2
- 9/12+10/12=19/12=1/7/12
