# 12.6 Outliers  (Page 5/11)

 Page 5 / 11
• Card 5 / 11:
The height (sidewalk to roof) of notable tall buildings in America is compared to the number of stories of the building (beginning at street level).

Using “stories” as the independent variable and “height” as the dependent variable, make a scatter plot of the data.Does it appear from inspection that there is a relationship between the variables?Calculate the least squares line. Put the equation in the form of: ŷ = a + bxFind the correlation coefficient. Is it significant?Find the estimated heights for 32 stories and for 94 stories.Based on the data in , is there a linear relationship between the number of stories in tall buildings and the height of the buildings?Are there any outliers in the data? If so, which point(s)?What is the estimated height of a building with six stories? Does the least squares line give an accurate estimate of height? Explain why or why not.Based on the least squares line, adding an extra story is predicted to add about how many feet to a building?What is the slope of the least squares (best-fit) line? Interpret the slope.

Sixty-four third year high school students were given a standardized reading comprehension test. The mean and standard deviation obtained were 52.27 and 8.24, respectively. Is the mean significantly different from the population mean of 50? Use the 5% level of significance.
No
Ariel
how do I find the modal class
look for the highest occuring number in the class
Kusi
the probability of an event occuring is defined as?
The probability of an even occurring is expected event÷ event being cancelled or event occurring / event not occurring

what is simple bar chat
Simple Bar Chart is a Diagram which shows the data values in form of horizontal bars. It shows categories along y-axis and values along x-axis. The x-axis displays above the bars and y-axis displays on left of the bars with the bars extending to the right side according to their values.
statistics is percentage only
the first word is chance for that we use percentages
it is not at all that statistics is a percentage only

I need more examples
how to calculate sample needed
mole of sample/mole ratio or Va Vb

how to I solve for arithmetic mean
Yeah. for you to say.
James
yes

how do I solve for arithmetic mean
niharu
add all the data and divide by the number of data sets. For example, if test scores were 70, 60, 70, 80 the total is 280 and the total data sets referred to as N is 4. Therfore the mean or arthritmatic average is 70. I hope this helps.

*Tan A - Tan B = sin(A-B)/CosA CosB ... *2sinQ/Cos 3Q = tan 3Q - tan Q

what is sampling? i want to know about the definition of sampling.
what is sample...?
In terms of Statistics or Research , It is a subset of population for measurement.
Da
can you solve this problem
yes
