The table below lists those cents portions categorized according tothe indicated values. Use a 0.025 significance level to test the claim that the four categories are equally likely. The person expected that many checks forwhole dollar amounts would result in a disproportionately high frequency for the first category, but do the results support that expectation?Cents portion of check0-2425-4950-7475-99Number31242223Click here to view the chi-square distribution table......The test statistic is(Round to three decimal places as needed.)

Indicate for each which type of t test is appropriate (independent, dependent). An educator would like to assess the effectiveness of a new instructional program for reading. The control group consist of n= 4 second grade students who are provided with the traditional instruction used at school. Later these students are given the experimental instruction and measured again on reading.

To test whether the mean time needed to mix a batch of material is the same for machines produced by three manufacturers, the Jacobs Chemical Company obtained the following data on the time (in minutes) needed to mix the material. Compute the values below (to 2 decimals, if necessary). Sum of Squares, Treatment Sum of Squares, Error Mean Squares, Treatment Mean Squares, Error Calculate the value of the test statistic (to 2 decimals). 1 19 25 23 21 Manufacturer a. Use these data to test whether the population mean times for mixing a batch of material differ for the three manufacturers. Use a = 0.05. What conclusion can you draw after carrying out this test? - Select your answer - 2 30 28 33 29 3 21 20 24 23 The p-value is - Select your answer - V What is your conclusion? - Select your answer - b. At the a= 0.05 level of significance, use Fisher's LSD procedure to test for the equality of the means for manufacturers 1 and 3. Calculate Fisher's LSD Value (to 2 decimals).

K Before every flight, the pilot must verify that the total weight of the load is less than the maximum allowable load for the aircraft. The aircraft can carry 41 passengers, and a flight has fuel and baggage that allows for a total passenger load of 6,765 lb. The pilot sees that the plane is full and all passengers are men. The aircraft will be overloaded if the mean weight of the passengers is greater than 6,765 lb 41 Should the pilot take any action to correct for an overloaded aircraft? Assume that weights of men are normally distributed with a mean of 183.6 lb and a standard deviation of 35.4. The probability is approximately (Round to four decimal places as needed.) ONCORPURINE MIMPIETARTUST SAMPARADE HOMENOT MANCHEIDU WARMTPARASH PRES = 165 lb. What is the probability that the aircraft is overloaded?
