4) A set of measurements is given as follows. X = [0.1, 0.3, 0.8, 12,4, 7,9] We want to approximate the source of this data with Gamma distribution, i.e., X~Gamma(a, B). For Gamma distribution, the mean and variance can be found from the below equations. a Hx a o = Find the parameters of Gamma distribution to fit the data. Come up with two other distributions that you think are good representation of this data. Justify your answer.

In the US, 46.2% of all people have type O blood, 39.1% have type A blood, 10.4% have type B blood and 4.3% have type AB blood. A researcher wants to see if the distribution of blood type is different for millionaires. The table below shows the results of a random sample of 3116 millionaires. What can be concluded at the a = 0.01 significance level? a. Complete the table by filling in the expected frequencies. Round to the nearest whole number: Frequencies of Blood Type Outcome Frequency Expected Frequency 1434 A 1224 В 310 AB 148 b. What is the correct statistical test to use? Select an answer V c. What are the null and alternative hypotheses? Но: O Blood type and income are independent. O The distribution of blood type for millionaires is not the same as it is for Americans in general. O The distribution of blood type for millionaires is the same as it is for Americans in general. O Blood type and income are dependent.

Hello, I need a little help trying to figure out how to get the Deviation from Mean and calculations.  I would appreciate any assistance so that I can understand the lab.

ALPHA = 0.05             Shift       1 2 3   Machine A 10 7 9   B 10 7 6   C 8 8 6   D 12 7 10   E 8 7 7   F 9 6 10   G 9 9 11   H 9 6 9               Often frequency data are tabulated according to two categories to decide if there is a relationship between categories and counts.  Machine shop high tech errors are tabulated by shift and machine with significance level a. Are the machines and shifts operating consistently?  Perform appropriate test.

suppose the mean is 8 and 1/3 and the population variance is 6 and 8/9 and a>9 x 5 9 a frequency 3 f 2 a=? f=?

i was wondering if i could get help with questions a and b

Step 2 of 3: Compute the Value of the test statistic. Round your answer to three decimal places.   Step 3 of 3: Draw a conclusion and interpret the decision

Please help solve question 4 attached in picture.

I need help with this parts a,b, and c please
