A 8. The level of dissolved oxygen in a river is an important indicator of the water's ability to support
aquatic life. You collect water samples at 15 randomly chosen locations along a stream and
measure the dissolved oxygen. Here are your results in milligrams per liter;
4.53, 5.04, 3.29, 5.23, 4.13, 5.50, 4.83, 4.40, 5.42,6.38, 4.01, 4.66, 2.87, 5.73, 5.55
Construct and interpret a 95% confidence interval for the mean dissolved oxygen level for this
stream.

Segment ab is shown on the graph. which shows how to find the x-coordinate of the point that will divide ab into a 2: 3 ratio using the formula

Someone answer asap for ! 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.
