Evaluate this expression
Answers
The value of the expression is [(6^3 - 9)/23]4 = 36
How to evaluate the expression?The expression is given as:
[(6^3 - 9)/23]4
Evaluate the exponent
[(6^3 - 9)/23]4 = [(216- 9)/23]4
Evaluate the quotient and the difference
[(6^3 - 9)/23]4 = [9]4
Evaluate the product
[(6^3 - 9)/23]4 = 36
Hence, the value of the expression is [(6^3 - 9)/23]4 = 36

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
Answers
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.
