Use the given degree of confidence and sample data to construct a confidence interval for the population mean μ. assume that the population has a normal distribution. the football coach randomly selected ten players and timed how long each player took to perform a certain drill. the times (in minutes) were: 7.0 10.8 9.5 8.0 11.5 7.5 6.4 11.3 10.2 12.6 determine a 95% confidence interval for the mean time for all players.

The quadratic function h(t)=-16.1t^2+150 choose the graph representation

Now max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
