Which measure of central tendency is used to calculate your grade-point average? a. standard deviation b. median c. mean d. z-score e. mode

On a certain portion of an experiment, a statistical test result yielded a p-value of 0.18. what can you conclude? 2(0.18) = 0.36 < 0.5; the test is not statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 18% of the time, so the test is not statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 82% of the time, so the test is not statistically significant. 0.18 > 0.05; the test is statistically significant. p = 1 - 0.18 = 0.82 > 0.05; the test is statistically significant.

Type the correct answer in each box. use = 3.14 and if necessary, round your answers to the nearest hundredth. the area of the largest cross section of a sphere and the circumference of the sphere are in the ratio 4: 1. cm. the area of the largest cross section is about the radius of the sphere is cm. the circumference of the sphere is about cm2. the volume of the sphere is about cm?
