Describe the importnat features of the distribution by identifying the mode, overall shape, and outliers. a. Which measure of center (mean or median) and which measure of variability (Standard deviation or IQR) would be best to describe the distrubution and why?

A psychologist wants to estimate the mean age at which a child learns to talk. Find the sample size necessary for a 95% confidence level to ensure that the sample mean is within 8 weeks for the mean age at which a child learns to talk. Assume sigma as 5 weeks.

Researchers studied the mean egg length (in millimeters) for a bird population. After taking a random sample of eggs, they obtained a 95% confidence interval of (45,60). What is the value of the margin of error? Choose the correct answer below. A. 15 mm B. 52.5 mm O c. 7.5 mm O D. 1.96

Cost of Building a Home According to the National Association of Home Builders, the average cost of building a home in the Northeast is $117.91 per square foot. A random sample of 42 new homes indicated that the mean cost was $123.87 and the standard deviation was $15. Can it be concluded that the mean cost differs from $117.91, using the 0.05 level of significance? Use the P-value method. Use a graphing calculator. Find the P-value. Round the answer to at least four decimal places. P-value=

The accompanying histogram shows the lengths of hospital stays​ (in days) for all female patients admitted to a certain hospital during one year with a primary diagnosis of acute myocardial infarction​ (heart attack). Complete parts​ (a) through​ (c) below.   ​a) From the​ histogram, determine whether the mean or median is larger. Explain.     A. Because the distribution is nearly symmetric​, the mean is expected to be larger than the median.   B. Because the distribution is nearly symmetric​, the mean is expected to be about the same as the median.   C. Because the distribution is skewed to the high end​, the mean is expected to be larger than the median.   D. Because the distribution is skewed to the high end​, the mean is expected to be smaller than the median.   E. Because the distribution is skewed to the low end​, the mean is expected to be larger than the median.   F. Because the distribution is skewed to the low end​, the mean is expected to be…
