the one-sample z-test to determine whether the hypothesized population proportion differs significantly from the observed sample proportion. Analyze Sample Data Using sample data, find the test statistic and its associated P-Value. * Standard deviation. Compute the standard deviation (σ) of the sampling distribution. σ = sqrt[ P * ( 1 - P ) / n ] where P is the hypothesized value of population proportion in the null hypothesis, and n is the sample size. * Test statistic. The test statistic is a

Part 1 First to get started with the project three 1.69 ounce bags of plain M&M’s were purchased from Walgreens, Rite-Aid and Dollar General. These bags will help with taking a sample of the population that is produced. Purchasing the bags from three different stores will help with the results of the project being meaningful because it is assured that the samples will be truly random. Random sampling is when all members of a group have an equal and independent chance of being selected. Next each

The equation used to determine sample size is n= Z2 * Standard Deviation2/(Standard Error)2. Z depends on the confidence required which is 1.96 for a confidence limit of 95% and n is the sample size. The standard

Determine the probability that a lot weights between 42 and 45 grams Mean and Standard Deviation µ=(a+b)/2 σ=(b-a)/sqrt(12) Section 6.2 Normal Distribution Example The GMAT is widely used by graduate schools of business as an entrance requirement. Assuming the scores are normally distributed, the mean GMAT score was 494 and standard deviation was 100. a) What is the probability a randomly selected score of the GMAT was greater than 700? b)

similar tables there. Firstly, we got monthly returns of 200 stocks in ASX from data stream, and used them to calculated standard deviations. Moreover, the table 1 was made out below (in order to maintain a neat, all the data we retain all four decimal places.) In the first table, when we made eight stocks as a portfolio, the rate of portfolio standard deviation to standard deviation of a single stock has been nearly 50%. We also found that the ratio will be constant at 0.2217 if we make more
