- Hallux abducto valgus (call it HAV) is a deformation of the big toe that often requires surgery. Doctors used X-rays to measure the angle (in degrees) of deformity in 38 consecutive patients under the age of 21 who came to a medical center for surgery to correct HAV. The angle is a measure of the seriousness of the deformity. Here are the data. 282014 311930 271429 351919 362451 271525 273128 172726 302130 282239 292030 131920 1825 It is reasonable to regard these patients as a random sample of young patients who require HAV surgery. Carry out the Solve and Conclude steps of a 95% confidence interval for the mean HAV angle in the population of all such patients. (Round your answer for x to two decimal places and your answer for s to three decimal places. Round your confidence interval bounds to two decimal places.)not use ai pleaseParellelogram EFGH is a dilation of parellelogram ABCD. What is the scale factor, K?

Researchers studied the bone mineral density (BMD) and depression of men aged 65 to 92 years. At the 1% significance level, do the data in the table (taken from a random sample) provide sufficient evidence to conclude that BMD and depression are statistically dependent for elderly men? Click on the icon to view the data table. What are the null and alternative hypotheses? O A. Ho: BMD is dependent upon depression in elderly men. H₂: Depression is dependent upon BMD in elderly men. B. Ho: Depression and BMD in elderly men are statistically dependent. H₂: Depression and BMD in elderly men are statistically independent. O C. Ho: Depression and BMD in elderly men are statistically independent. H₂: Depression and BMD in elderly men are statistically dependent. Find the test statistic. x² = Find the P-value.
