For
this Assignment complete two problems that involve calculating confidence
intervals with one sample.1.The
first problem involves calculating and interpreting the 90% 95% and 99%
confidence intervals for a one-sample t-test.
2.The
second problem involves calculating and interpreting the 95% confidence
interval for a proportion.

3.While
you can use SPSS to determine proportions you need to calculate the confidence
interval by hand.Answer the following
problems:Problem 4.1:Given
the data set body-weight.sav use SPSS to calculate the 90% 95% and 99%
confidence intervals for the mean of the variable weight. Interpret the three
confidence intervals in terms of whether there is a significant difference
between the mean of the sample and a hypothesized mean of 150.Problem 4.2:Every year the CDC conducts phone surveys to
assess the health risks of people in the U.S. This survey is abbreviated BRFSS
which stands for Behavioral Risk Factor Surveillance System. Review the
following data collected for 2009:Total

the proportion of each group of respondents.2.Calculate
the confidence interval for the proportion of respondents who stated they are
former smokers.
