independent variable. what is the independent variable? what are you deliberately choosing or changing?

1 answer:

8 0

The independent variable is the factor that you purposely change or control in order to see what effect it has. The variable that responds to the change in the independent variable is called the dependent variable. It depends on the independent variable. The independent variable is graphed on the x-axis.

To identify dependent studies variables, search for objects in your studies query or speculation that sees the result, effect, or outcome of changing the independent variable. The basic rule is to search for what reasons for reactions and what receives the results.

The statistical courting between variables is referred to as their correlation. A correlation might be high-quality, which means each variable circulates in the same direction, or bad, meaning that once one variable's price will increase, the opposite variables' values decrease.

Making sure that certain research variables are managed will increase the reliability and validity of the test, by ensuring that other causal consequences are removed. This safeguard makes it simpler for other researchers to repeat the experiment and comprehensively test the results.

Find the equation of the line passing through the points A(3,2) and B(6,3)

icang [17]

Answer:

y = $\frac{1}{3} x+1$

Step-by-step explanation:

m = $m = \frac{change in y}{change in x} \\m = \frac{3 - (2)}{6 - (3)}\\m = \frac{1}{3} \\Find the value of b using the equation of a line \\y = mx+b\\y =( \frac{1}{3} )x + b\\2 =( \frac{1}{3} ) * (3) + b\\cancel common factor\\1 + b = 2\\b = 1\\y = \frac{1}{3} x + 1$

Over [174]

Answer:

A(x) = 20000(0.88)^x

Step-by-step explanation:

The general form of these exponential equations is ...

A(x) = a·b^x

where 'a' is the initial value, and b is the annual growth factor. x is the elapsed time in years.

The growth factor is ...

growth factor = 1 + growth rate

Here, the growth rate per year is -12%, so the growth factor is ...

b = 1 -12% = 88% = 0.88

Of course, the initial value is a=20,000, so the equation is ...

A(x) = 20000(0.88)^x

Grades on a standardized test are known to have a mean of 1000 for students in the United States. The test is administered to 45

krok68 [10]

Answer:

The 95% confidence interval is $1003 < \mu$

Yes there is statistically significant evidence that students in Florida perform differently from other students in the United States

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 1000$

The sample size is $n = 453$

The sample mean is $\= x = 1013$

The standard deviation is $s = 108$

Given that the confidence level is 95% then the level of significance is mathematically represented as

$\alpha = 100 - 95$

=> $\alpha = 5\%$

=> $\alpha = 0.05$

The critical value for $\frac{\alpha }{2}$ obtained from the normal distribution table is

$Z_{\frac{\alpha }{2} } = 1.96$

Generally the margin of error is mathematically represented as

$E = Z_{\frac{\alpha }{2} } * \frac{s}{\sqrt{n} }$

=> $E = 1.96 * \frac{108}{\sqrt{453} }$

=> $E = 9.946$

Generally the 95% confidence interval is mathematically represented as

$\= x - E < \mu < \= x + E$

=> $1013 - 9.946 < \mu < 1013 + 9.946$

=> $1003 < \mu$

Given that the population mean(1000) is not within the 95% confidence interval for l for the average test score for students in Florida, then it means that there is statistically significant evidence that students in Florida perform differently from other students in the United States
