(1 point) For the data set (−2,−3),(1,0),(6,6),(9,6),(12,8),
find interval estimates (at a 92.4% significance level) for single
values and for the mean value of y corresponding to x=5.
Note: For each part below, your answer should use interval
notation.

Data Set A- 7,7,7,9,9,9,10
Data Set B- 4,6,6,6,8,9,9,9,10,10,10
Step 1
Create a bar graph that examines a variable or variables in
your data set.
Step 2
Find the sample mean, median (if it exists) mode for each set
of data
Next find the sample standard deviations for each set of
data
Create a box and whisker plot for each variable for each set

In a survey sample of 1,000 respondents, the mean annual salary
is $32,245, with a standard deviation of 4021.54. By a step by step
process:
1. Estimate the value of the standard error
2. Calculate a 95% confidence interval for these data. (0.25
