A 0.01 significance level is being used to test a correlation between two variables. If the linear correlation coefficient r is
1 answer:
Answer:
There is sufficient evidence that there is linear correlation between two variable
Step-by-step explanation:
From the question we are told
The significance level is
The critical value is
The test statistics is (linear correlation coefficient )
Now from the data given in the value we see that
so the null hypothesis is rejected
Hence the conclusion is that there is sufficient evidence that there is linear correlation between two variable

6. Multiply the given equation by 20
... 20×1 in. = 20×2.54 cm
... 20 in = 50.8 cm
7. Multiply the equation (1 foot = 12 inches) by 25.
... 25×1 ft = 25×12 in
... 25 ft = 300 in
Now, multiply the equation for conversion to cm by 300
... 300×1 in = 300×2.54 cm
... 300 in = 762 cm
Using the transitive property of equality,
... 25 ft = 300 in = 762 cm
... 25 ft = 762 cm

A "unit multiplier" is no doubt explained in your lesson. We assume it is a fraction whose value is 1, but that has different units in numerator and denominator. The equation 1 in = 2.54 cm gives rise to two unit multipliers, depending on which conversion you need or want:
Since you're converting <em>to</em> centimeters, you want the one with <em>cm</em> in the numerator.
