Your friend says that the mass of any object is distributed symmetrically around its center of mass. Design an experiment to test your friend's idea. You have a meter stick, a set of small objects of different masses, masking tape, and a mass measuring scale. Describe your experiment and predict the outcome based on your friend's ide

I am asking for help on the final 3 bullets points starting with: "State whether the results..." and ending with "Explain what the results of the test mean, using words other than..." Here is the data and scenario: A biologist believes that the population of rats in a subway tunnel may actually be a new subspecies because they appear to be heavier than those above ground. Here are the statistics, for the weight in ounces, from two samples gathered: Rats in tunnel: Rats above ground: n = 97 n = 76 Mean1 = 29.1 Mean2 = 28.3 S.Dev1 = 2.7 S.Dev2 = 2.4 Does she have have enough evidence to conclude that the subway rats are heavier on average? What is the relationship between this test and the confidence intervals for the two means?
You conduct an experiment in which randomly selected young women are solicited in the street by a good-looking young man who approaches each woman with the following line: "Excuse me! I think you look ravishingly pretty! I just thought you might be happy to know... I'm going to work now, but do you think we could have a drink somewhere in the afternoon? If you give me your phone number, I'll ring you up." It is recorded whether the woman complies with the man's request and shares her phone number with him. The purpose of the experiment is to find out whether women's decisions are influenced by what the man is wearing. You test a random sample of 50 women under each of the following conditions: (A) the man is wearing an elegant suit, (B) the man is wearing casual clothes but well-known and expensive brands, (C) the man is wearing no-name jeans and a T-shirt. A chi-square test is conducted in SPSS and yields the following output: Compliance Clothes Crosstabulation Count Compliance. Total…
what would be also the decision and conclusion for this?
If P( A) = .40, P( B) = .30, and P AOB) = .15, then P( AI B) is .375 .12 .50 .045
Hello. Could anyone help me on this question? I have tried it four times and only one attempt left. What I am confusing is that some choice are not individual and variables. Like all young children, children who eat snack and cartoon characters. But if i leave them there, it shows me I am wrong. Pls help me on this and explanation would be appreciated. Thanks!
Use the following information to answer the next four problems: In an experiment, 1919 babies were asked to watch a climber attempt to ascend a hill. On two occasions, the baby witnesses the climber fail to make the climb. Then, the baby witnesses either a helper toy push the climber up the hill, or a hinderer toy preventing the climber from making the ascent. The toys were shown to each baby in a random fashion. A second part of this experiment showed the climber approach the helper toy, which is not a surprising action, and then the climber approached the hinderer toy, which is a surprising action. The amount of time the baby watched the event was recorded. The mean difference in time spent watching the climber approach the hinderer toy versus watching the climber approach the helper toy was 105 seconds with a standard deviation of 195 seconds. State the null and alternative hypotheses to determine if babies tend to look at the hinderer toy longer than the helper toy. Let…

Barry has several Christmas Cactus houseplants. He heard a rumor that they will bloom better if they are put in a dark room from October to November. What experiment could Barry design to test his hypothesis?
