Suppose there are 1,323 subjects in a particular category (nc = 1,323), and there are a total of 6,300 total subjects in the sample, (n = 6300). Compute the relative frequency of this category.

They sampled 361 people. People were allowed to self-identify as a heavy smoker or a non-smoker (mutually exclusive outcomes), and as diagnosed with lung cancer or not diagnosed with lung cancer (mutually exclusive outcomes). All surveyed people were under the age of 55, with similar age distributions in the smoking and not smoking categories. 343 people said that they did not smoke, and of those 343 people, 58 had been diagnosed with lung cancer. Only 18 people said  that they were heavy smokers, and of those 18, 14 had been diagnosed with lung cancer. Please Calculate the expected count of people for each cell of the contingency table if the standard null hypo of the chi-square test of independent comes out to be true?

A researcher is interested in the relationship between birth order and personality. A sample of n= 100 people is obtained, all of whom grew up in families as one of three children. Each person is given a personality test, and the researcher also records the person’s birth-order position (1st born, 2nd, or 3rd). The frequencies from this study are shown in the following table. On the basis of these data, can the researcher conclude that there is a significant relation between birth order and personality? Test at the .05 level of significance.   Birth  Position     1st 2nd 3rd Outgoing 13 31 16 Reserved 17 19 4 The critical value is:                                                                                                                                                                                                                                                                               Our calculated chi-square is:…

Suppose that a polling company surveyed 600 people about how much time they spend watching television each day. The results of this survey were compiled and used to create this relative frequency histogram.   Assume that all percentages shown in the histogram are whole numbers. Each of the bars in this histogram includes only the left endpoint of the class except for the last bar, which also includes the right endpoint. What percentage of respondents said that they watch television at least six hours per day? How many respondents said that they watch television between three and five hours per day?

Suppose there are 1,323 subjects in a particular category (nc = 1,323), and there are a total of 6,300 total subjects in the sample, (n = 6300). Compute the relative frequency of this category. For credit your answer must be a decimal, accurate to two decimal places. If your answer is less than 1 there must be a zero before the decimal point. Type your answer...

In a study, it was found that 42.5% of the population drink soda at least once a day. You randomly select 8 people. Let X be the number of people in the sample that drink soda at least once a day.Then X has what distribution?

Among fatal plane crashes that occurred during the past 55 years, 348 were due to pilot​ error, 66 were due to other human​ error, 597 were due to​ weather, 104 were due to mechanical​ problems, and 148 were due to sabotage.  Construct the relative frequency distribution. What is the most serious threat to aviation​ safety, and can anything be done about​ it?
