The strongest finding from the data was that the top 10 finishes occurred as the top predictor of winnings among the drivers. The p-value of 0.0068 provides a significant relationship and its relatively high, \( t \)-statistics of 2.91 , compared to other variables. Poles, Wins, and Top 5 finishes were expected to give us more predictive power, but showering the low \( t \)-stats, suggesting weak or no true relationship to the winnings. Based on these findings while wins and poles are important for achieving overall success in NASCAR, they do not appear to directly drive winnings as strongly as top 10 finishes. To support this, the regression model demonstrated the coefficient for the top 10 finishes. The top 10 finish is associated with an increase of \( \$ 112,822 \) in winnings. The substantial contribution compared to the negligible coefficients for poles or wins, reinforces the importance of consistency over singular achievements.I Review your peer's post.

15. Suppose data collected for heights (in cms) of 390 cows were tabulated in a frequency distribution and the following results were obtained. fi: \( 6,25,48,72,116,60,38,22,3 \) CMI \( =112, \mathrm{CM} 2=117 \) where CMi ith class mark Determine: a) Class interval size (class width), Class limits, Class boundaries and class marks b) The less than cumulative frequency distribution c) The class intervals having the highest frequency d) Above which height do we find \( 50 \% \) of the cows? c) Below which height do we get \( 25 \% \) of the cows? Draw a) histogram b) a frequency polygon c) C. a less than ogive for the above data

(b) Hitung sisihan piawai bagi tinggi, dalam cm , murid tingkatan 5 Kristal dengan diteri silai min ketinggian murid tersebut adalah 155.5 cm . Calculate the standard deviation of the height, in cm , of pupils in form 5 Kristal by given the mean value of the height of the pupils is 155.5 cm . [3 markah/ marks] (c) Dengan menggunakan skala 2 cm kepada 5 cm pada paksi mengufuk dan 2 cm kepada seorang murid pada paksi mencancang, lukis histogram bagi maklumat tersebut. Using a scale of 2 cm to 5 cm on the horizontal axis and 2 cm to a pupil on the vertical cris, draw a histogram for the information.
