Hello I am new to statistics and probability please help me as i am struggling on my practice questions. I feel like i have all the wrong final answers

Part A

Information has been collected on the number of civil disturbances (riots, strikes, operation occupy, etc.) over the past year and on unemployment rate [95} in 10 cities. Are these variables linearly related? The data are presented in the following table. UnemploymentRalie[%] 25 21 20 22 16 1D 13 12 19 14 Civil Disturbances 15 15 13 13 5 8 13 6 15 14 The coefficient of determination for this data is r2 = 0.3322 and the regression equation is: fr = 3.3529 + 0.48533. For part (a), express your answer in percent form (i.e. 3.00% instead of 0.03) and round to 2 decimal places. {a} What percent of the variation in sales cannot be explained due to the other factors? C] % For parts (b) and (c), round to 4 decimal places. {b} Calculate the correlation coefficient 1" = C] {c} What is the slope of the equation? C] For part (d), round your final answer to 3 decimal places. {d} Predict the number of civil disturbances in a city with 9% unemployment rate.? :1 The following scatter plot shows the weight [in pounds] and the number of hours slept in a day by a random sample of infants. A pediatrician wants to know if there is any correlation between these two factors. Infants' weights and their number of hours of sleep 1' = \"1'5! + 15.981 145 . R, = 03152 O 2 4 6 3 10 12 14 16 weight [a] The independent variable is {b} The dependent variable is Round your answer for part [c] to 2 decimal places. {c} The value of the correlation coefficient is :] State the numerical part of your answer for part [d] accurate to 4 decimal places. {d} With every pound increase in an infant's weight, the number of hours of sleep by Round your answers for parts {e}, (f) to 2 decimal places and express your answers in percentage form (i.e. 3.00% instead of 0.03). {e} What percentage of total variation in the number of hours slept in infants can be explained by their weight? {fl Predict the number of hours of sleep in a day by an infant who weighs 9 pounds
