an you tell how old a lobster is by its size? This question was investigated by the authors of a paper that appeared in the Biological Bulletin (August 2007). Researchers measured carapace (the exterior shell) length of 27 laboratory-raised lobsters of known age. The data on x = carapace length (in mm) and y = age (in years) in the following table were read from a graph that appeared in the paper. Age CarapaceLength Age CarapaceLength Age CarapaceLength 1.00 63.32 1.82 118.25 2.93 147.82 1.00 67.50 2.18 108.24 2.92 140.17 1.00 69.58 2.18 109.64 2.92 135.73 1.00 74.41 2.17 117.99 2.92 121.81 1.42 80.32 2.17 123.81 3.17 141.30 1.42 81.80 2.33 138.47 3.41 151.73 1.42 84.59 2.50 133.95 3.42 145.78 1.82 105.07 2.51 124.25 3.75 147.21 1.82 106.16 2.50 123.51 4.08 152.04 (a) Construct a scatterplot of these data, and then find the equation of the least squares regression line that describes the relationship between y = age and x = carapace length.

Range of ankle motion is a contributing factor to falls among the elderly. Suppose a team of researchers is studying how compression hosiery, typical shoes, and medical shoes affect range of ankle motion. In particular, note the variables Barefoot and Footwear2. Barefoot represents a subject's range of ankle motion (in degrees) while barefoot, and Footwear2 represents their range of ankle motion (in degrees) while wearing medical shoes. Use this data and your preferred software to calculate the equation of the least-squares linear regression line to predict a subject's range of ankle motion while wearing medical shoes, ?̂ , based on their range of ankle motion while barefoot, ? . Round your coefficients to two decimal places of precision. ?̂  = A physical therapist determines that her patient Jan has a range of ankle motion of 7.26°7.26° while barefoot. Predict Jan's range of ankle motion while wearing medical shoes, ?̂ . Round your answer to two decimal places. ?̂ = Suppose Jan's…

The table below displays the adult literacy rate in Bolivia for several different years. The adult literacy rate is the percentage of people ages 15 and above who can both read and write with understanding a short simple statement about their everyday life. Data downloaded on 2/19/2020 from https://ourworldindata.org/grapher/literacy-rate-adults?tab=chart&time=1973..2016. Year 1976 2001 2012 Literacy Rate 63.2% 86.7% 94.5% When answering the questions below, round to four decimal places in your intermediate computations. Use interpolation or extrapolation (whichever is appropriate) to predict the literacy rate in Bolivia in 1992. Round your answer to one decimal place. You only get one submission for the unit. ---Select--- Use interpolation or extrapolation (whichever is appropriate) to predict the literacy rate in Bolivia in 2050. Round your answer to one decimal place. You only get one submission for the unit. ---Select--- Is your 2050 prediction realistic? You must…

Measuring the height of a California redwood tree is very difficult because these trees grow to heights of over 300 feet. People familiar with these trees understand that the height of a California redwood tree is related to other characteristics of the tree, including the diameter of the tree at the breast height of a person. The data in the table represent the height (in feet) and diameter (in inches) at the breast height of a person for a sample of 21 California redwood trees. Assuming a linear relationship, use the least- squares method to compute the regression coefficients b0 and b1. State the regression equation that predicts the height of a tree based on the tree’s diameter at breast height of a person. Interpret the meaning of the slope in this equation. Predict the mean height for a tree that has a breast height diameter of 25 inches.
