A t-test compares means between two samples, while also considering the variation around each mean. You will use Excel to run the t-test, but it is important to note the actual equation Excel is using: Where X = sample mean and s = standard deviation, and n = sample size. Statistical analysis. Open the Excel spreadsheet . Ice_Off_Date.xls ...

The graph shows that the distribution of the rate of return of Exxon appears not markedly different from a normal distribution at least in the middle part. The procedure described above is easy to understand, but is not effective for revealing a subtle but systematic departure of the histogram from normality.

The following graph shows the Poisson distribution with mean of 5 and the normal distribution with a mean of 5 and standard deviation equal to 2.2361 (the square root of 5): Again if using the normal distribution to compute probabilities for the Poisson distribution one must correct for continuity in the same way as was done for the binomial ...

2. The random number generator in Excel is set to produce numbers at random from 4 to 20 using a uniform distribution. Let the random variable U denote the value of a uniform random number. For the problems given below, draw a graph of the situation, and use function notation to communicate what you are doing. a.

Draw the normal distribution graph and define your rejection area. Ho: = 35. Ha: ≠ 35 = 0.05. We will use Z at = 0.05, alpha has to be divided by the 2 tails of the distribution. Use excel ( =NORMSINV(0.05/2) =NORMSINV(0.25)= + 1.96 . If Ztest > +Z Or if Ztest < - Z , Reject Ho otherwise Don’t reject it ...
How To Make Normal Distribution Graph in Excel? (With Examples)
The distribution is normal, or fairly normal, because a linear best-fit line plotted through the data points fits the data points quite well. The median is obtained by reading the measurement corresponding to the 50% point. This is about –1 as compared to the calculated median of –0.98.
