Chi-Square True/False Question Block

1) True or False: In a chi-square test, the "expected" counts are the values we expect if there is no association between the variables.

True

False

2) True or False: A small chi-square test statistic provides evidence against the null hypothesis.

True

False

3) True or False: If a chi-square test is significant (i.e., there is an association between the variables), we should look at the chi-square components as a follow-up analysis.???????

An asphalt plant can produce 400 tph. A paving project requires paving individual 12ft lanes with a 2-in. lift averaging 140 lbfsy-in. What average paver speed will match the plant production? How many ZU-ton dump trucks will he required if the total hauling cycle time is 50 minutes? Which is not associated with strong vertical patterns in species occurrence or diversity? O Pelagic zones O Salt marshes O Intertidal zones Mangroves O Lakes D Question 4 2 pts What best explains how most of the wetlands, ponds and lakes of the Prairie Pothole region of North America were formed? O Soil deposited by glaciers formed rims that impounded water O Continental glaciers scoured out large basins that filled with water O Small cirques carved out of bedrock filled with water Stranded glacier ice chunks buried in glacial soil deposits left depressions filled with waterl. A Small plant has a mean daily production of 700 tons with a standard deviation of 80 tons. A large plant has a mean daily production of 900 tons with a standard deviation of 100 tons. Assuming daily production is normallyr distributed at each plant, find the probability that {a} the average dailyr production for the next: 12 days at the small plant will exceed 750 tone, and (b) the average daily production for the next: 7 days at the large plant will exceed the average daily production for the next 12 days at the small plant by 180 tone or less
