# Question

Data Set 13 in Appendix B includes crash test measurements for small cars. The seven chest deceleration measurements have a mean of 42.7 g and a standard deviation of 5.6 g, where g is a force of gravity. Use the sample data to construct a 95% confidence interval estimate of the mean chest deceleration measurement for the population of all small cars. (Assume that the sample is a simple random sample and the measurements satisfy the loose requirement of being from a normally distributed population.) Write a brief statement that interprets the confidence interval.

## Answer to relevant Questions

Refer to the sample data described in Exercise and construct a 95% confidence interval estimate of the population standard deviation. Listed below are HDL and LDL cholesterol measurements (all in mg/dL) from 10 randomly selected women (based on Data Set 1 in Appendix B). Also shown is a scatter plot of the paired data. Based on the scatter plot does there ...When parents use the XSORT method of gender selection, the proportion of baby girls is greater than 0.5. dhe latest actual results show that among 945 babies born to couples using the XSORT method of gender selection, 879 ...The test statistic of z = 1.50 is obtained when testing the claim that p ≠ 0.25.
