Answer:
Step-by-step explanation:
For one, there can only be two variables, for two, two variables cannot be multiplied together. For example, xy + 2z= 4 is not linear.
Answer:
13
Step-by-step explanation:
7 x 2=14
40-14=26
26/2=13
Y=-4x+1 is this what you wanted?
Since null hypothesis on this data is not rejected.
<h3>Null and Alternative Hypothesis</h3>
Data;
- sample mean x1 = 240993
- population standard deviation σ1 = 25875
- sample size n1 = 35
- sample mean x2 = 249237
- population standard mean σ2 = 27110
- sample size n2 = 35
- significance level α = 0.10
H_o = μ1 = μ2
H_o = μ1 ≠ μ2
This is a two-tailed test and population standard deviation will be used.
<h3>Test Statistic</h3>
The z-stat is
The significance level is α = 0.1 and the critical value for a two-tailed test is
Since , we can assume that the null hypothesis is not rejected.
