I'm struggling a little bith in Math. Can someone help me to understand how to calculate MAD (mean absolute deviation)?
Answer:It can be calculated by finding the mean of the values first and then find the difference between each value and the mean. Take the absolute value of each difference and find the mean of the difference, which is termed as MAD. Find the MAD of a data set using this mean absolute deviation calculator. MAD Calculator.

Complete Question
Although the first quarter of 2002 was quite dismal on Wall Street, mutual funds investing in gold companies rose an average of 35.2%. Assume that the distribution of returns in the first quarter of 2002 for mutual funds specializing in gold companies is fairly symmetrical with a mean of 35.2% and a standard deviation of 20%. If random samples of 16 gold stock funds were selected:
90% of the sample mean returns are between what two values symmetrically distributed around the mean?
Answer:
The two values symmetrically distributed around the mean are
21.87\% and 43.17\%
Step-by-step explanation:
From the question we are told that
The sample size is [tex]n = 16[/tex]
The sample mean is [tex]\= x = 0.352[/tex]
The standard deviation is [tex]\sigma = 0.20[/tex]
Generally the degree of freedom is mathematically represented as
[tex]df = n -1[/tex]
=> [tex]df = 16 -1[/tex]
=> [tex]df = 15[/tex]
From the question we are told the confidence level is 90% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.10[/tex]
Generally from the t distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] at a degree of freedom of [tex]df = 15[/tex] is
[tex]t_{\frac{\alpha }{2} , 15 } = 2.13 [/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]E = 2.13 * \frac{ 0.20 }{\sqrt{16} }[/tex]
=> [tex]E = 0.1065 [/tex]
Generally 90% confidence interval is mathematically represented as
[tex]0.3252 -0.1065 < \mu < 0.3252 + 0.1065 [/tex]
=> [tex]0.2187 < \mu < 0.4317 [/tex]
converting to percentage
[tex]0.2187 * 100 < \mu < 0.4317 * 100 [/tex]
=> [tex] 21.87\% < \mu < 43.17\% [/tex]
Hence the 90% of the sample mean returns are between 21.87\% and 43.17\%

What is the formula for calculating a residual value
The residual value indicates how well the regression model fits the observed data, with a residual of zero indicating a perfect fit.
In the context of linear regression analysis, the residual value represents the difference between the observed value of the dependent variable and the predicted value. The formula for calculating the residual value can be expressed as:
Residual = Observed Value - Predicted Value
To calculate the residual value, you need to have a regression model that predicts the value of the dependent variable based on the independent variable(s). Once you have the predicted value, you subtract it from the corresponding observed value to obtain the residual.
For example, if you have an observed value of 10 and the predicted value from the regression model is 8, the residual would be:
Residual = 10 - 8 = 2
The residual value indicates how well the regression model fits the observed data, with a residual of zero indicating a perfect fit.

If a, b are real numbers and 7a + i(3a - b) = 14 - 6i , then find the values of a and b.
If a, b are real numbers and 7a + i(3a - b) = 14 - 6i, then find the values of a and b. Therefore, the value of a = 2 and the value of b = 12. 3.
The value of the variables 'a' and 'b' of the complex equation will be 2 and 12, respectively.
What is a complex number?The complex number is the combination of the real part and the imaginary part. Then the complex number is given as a+bi where the value of i is √(-1) and the value of i² is -1.
The equation is given below.
7a + (3a - b)i = 14 - 6i
Compare the real part of the equation, then we have
7a = 14
a = 14 / 7
a = 2
Compare the imaginary part of the equation, then we have
3a - b = - 6
3 x 2 - b = -6
6 - b = - 6
b = 6 + 6
b = 12
The value of the variables 'a' and 'b' of the complex equation will be 2 and 12, respectively.

Solve the following quadratic equation
2x²+7x=15
Answer:
x = - 5 ; x = 3/2
Step-by-step explanation:
Start by subtracting 15 from both sides to get to an equation in standard form: a x^2 + b x + c= 0 so we can use the quadratic formula to solve for "x".
2 x^2 + 7x - 15 = 0
Then:
[tex]x=\frac{-7+/-\sqrt{49-4(2)(-15)} }{4} \\x=\frac{-7+/-\sqrt{169} }{4}\\x=\frac{-7+/-13}{4}\\x =-5\\or\\x=3/2[/tex]
