Answer:
The 95% confidence interval estimate of the population mean rating for Miami is (6.0, 7.5).
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for the population mean, when the population standard deviation is not provided is:
The sample selected is of size, <em>n</em> = 50.
The critical value of <em>t</em> for 95% confidence level and (<em>n</em> - 1) = 49 degrees of freedom is:
*Use a <em>t</em>-table.
Compute the sample mean and sample standard deviation as follows:
Compute the 95% confidence interval estimate of the population mean rating for Miami as follows:
Thus, the 95% confidence interval estimate of the population mean rating for Miami is (6.0, 7.5).
Answer:
x intercept = 8
y intercept = -24
Step-by-step explanation:
In the USA, the shoe sizes or men are approximated by the equation 3f-s=24, where f represents the length of the foot in inches and s represents the shoe size.
<u>When we represent this equation using a graph, we mark the independent variable on the x axis and the dependent variable on the y axis.</u>
Here the foot length is the independent variable and the shoe size is the dependent variable. Hence we take foot length on x axis.
To get x intercept put y=0, f = = 8 inches .
This is the point from which where we start our shoe size.
The y intercept , s = -24.
