Step-by-step explanation:
From the question we are told that
The first concentrations is
The second concentrations is
The first sample size is
The second sample size is
The first standard deviation is
The first standard deviation is
The mean for Turnpike is
The mean for Tunnel is
The null hypothesis is
The alternative hypothesis is
Generally the test statistics is mathematically represented as
Generally the degree of freedom is mathematically represented as
The significance is evaluated as
=>
=>
The critical value is evaluated as
From the student t- distribution table
So
=>
given that
we fail to reject the null hypothesis so this mean that the result do not differ
Answer:
Table N 4
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
<em>Verify the table 4</em>
For x=1, y=2
so
y/x=2/1=2
For x=2, y=4
so
y/x=4/2=2
For x=3, y=6
so
y/x=6/3=2
therefore
The constant of proportionality k is equal to 2 and the equation is equal to
y=2x
The table 4 represent a direct variation, therefore is a possible ratio table for ingredients X and Y
