You are given the following hypotheses. h0: μ = 40 ha: μ ≠ 40 we know that the sample standard deviation is 10 and the sample size is 60. for what sample mean would the p-value be equal to 0.05? assume that all conditions necessary for inference are satisfied. (round your answers to two decimal places.) smaller mean x = larger mean x = you may need to use t.

How is working backward similar to solving an equation?

Prism m and pyramid n have the same base area and the same height. cylinder p and prism q have the same height and the same base perimeter. cone z has the same base area as cylinder y, but its height is three times the height of cylinder y. the figures and have the same volume.

Astudent is determining the influence of different types of food on the growth rate of spiders. she feeds one group of spiders two caterpillars twice a week. the other group received similarly-sized beetles twice a week. she records the amount of time required for individuals to reach sexual maturity. her hypothesis is that the spiders feeding on caterpillars will have a faster growth rate because caterpillars have a higher protein content compared to beetles. in this experiment, what is the dependent variable? spiders assigned to different feeding groups. time required to reach sexual maturity number of prey items fed twice a week. growth rates of each group.
