Problem 2A random sample of 36 skeletal remains from females was taken from data stored in theForensic Anthropology Data Bank (FDB) at the University of Tennessee. The femur lengths(right leg) in millimeters are recorded below.432432 435 460 432 440 448 449 434 443525 451 448 443 450 467 436 423 475 435433 438 453 438 435 413 439 442 507 424468 419 434 483 448 514a. Determine the sample mean and standard deviation.Since the sample size is large, we can use the sample standard s in place of o in calculationsof confidence intervals.b. Before doing any calculations, think about a 90%, 95% and 99% confidence for u, the meanfemur bone length for women. Which of these intervals would be the widest? Which would bethe narrowest? Explain how you know without calculating the confidence intervals.c. Calculate 90%, 95%, and 99% confidence intervals for u, the mean femur bone length foradult females. Do your results confirm your answer to (b)?
