Refer to the correlation table for this question, The data come from Wave 5 of the Arab Barometer survey in Kuwait and were collected in 2019. In this analysis, we see the correlation between age and years of education (Pearson's R= -0.2729) with the p-value (0.0000) below. Explain what a correlation coefficient is and interpret the one you see here. edu_ye~s age edu_years 1.0000 age -0.2729 1.0000 0.0000
An ecologist is interested in exploring the relationship between pollination rate and the number of bees present at apple orchards. The relationship is: (Pollination rate) = 372.6 + 13.5 x (bees) with r = 0.80. The best interpretation of the correlation coefficient is: (pick one) 1. 64% of the variability in pollination rate observed at apple orchards is explained by the relationship with the number of bees 2. the correlation between pollination rate and number of bees is 0.64 3. 80% of the variability in number of bees at apple orchards is explained by the relationship with the pollination rate 4. the correlation between pollination rate and number of bees is 0.80

Fifty-four wild bears were anesthetized, and their weights and chest sizes were measured. Results are showing in the graph below. IS there sufficient evidence to support the claim that there is a linear correlation between weights of bears and their chest sizes? When measuring an anesthetized bear, is it easier to measure chest size than weight? If so, does it appear that a measured chest size can be used to predict the weight?

Manufacturing The Wellbuilt Company produces two types of wood chippers, economy and deluxe. The deluxe model require 3 hours to assemble and 1/2 hours to paint, and the economy model requires 2 hour to assemble and 1 hour to paint. The maximum number of assembly hours avaliable is 24 per day, and the maximum number of painting hours avaliable is 8 per day. if the profit on the deluxe model is $90 per unit and the profit on the economy model is $72 per unit, how many units of each model will maximize profit?
