Letting u represent the mean composite satisfaction rating for the XYZ-Box‚ set up the null hypothesis H0 and the alternative hypothesis Ha needed if we wish to attempt to provide evidence supporting the claim that µ exceeds 42. H0: mu 42 b. The random sample of 65 satisfaction rating yields a sample mean of x = 42.954. Assuming that s equals 2.64‚ use critical values

ABSTRACT: The lab of one dimensional motion is a series of experiments that deal with different types of motion in a single direction. In the first experiment‚ one dimensional motion of a small cart on an air track is measured in a one photogate system. The acceleration was calculated by the infrared light emitting electrode of the photogate sensing the slacks on the picket fence. The calculation for gravity yielded 9.63 m/s^2‚ which is consistent with the accepted value of 9.8m/s^2. In the

Are girls too mean to each other ? Are girls really “mean”?That’s the question. Many people assume girls are mean because they just don’t like that person and other people think that’s the way they were made to be. There are many disagreements on whether girls are mean or not. Girls are not mean because they might not savor you. It’s mostly because they either have a low self esteem or think their life or themselves is apathy. Some girls are just insecure and don’t know what to do so they let out

I chose the film Mean Girls for this assignment because I have already seen the film. With previous knowledge about the film‚ I knew that it was full of conflict and watching a movie I have previously seen allowed me to focus on the textbook and its concepts‚ rather than everything that was taking place in the film. Power without question is a major reason why conflict took place in Mean Girls and why it takes place in the real-world. Power is the structure of conflict and it is rare for people

evaluate that our bottles of water to determine if in fact our customers were right. We needed to evaluate a process that would help us to determine this. First we would evaluate the water bottles by conducting the mean of how many ounces of water were in each bottle. When discussing the mean in mathematical terms we find out what the quantity overall of a series of numbers given to us. For example:

and continue with the current method the other wing and after six months‚ compare the results. After the six month trial period‚ Tom and Sandra collected data from the two random samples. Each sample (represented by n1 and n2) produced sample means (represented by x1 and x2) and sample standard deviations (represented by s1 and s2) and this would determine whether the consistency of the employees has been affected by the new program. However‚ there is also concern on whether the job-enrichment

I would generally use whole-group instruction at the beginning of a lesson. This allows me to give the students a pre assessment on their knowledge on the subject. New information being introduced to the class should always be given in a whole group setting so as not to give any students a disadvantage of succeeding. By showing the whole class new concepts at the same time‚ it allows me to figure out what kind of flexible groupings I will need to implement. Typically within-class grouping would
