4. A research assistant measured 50 plant heights using a yard stick. She computed the average and the SD and obtained 32 and 2.1 inches, respectively. Later she realized that the yard stick was broken and the first six inches were missing. Consequently, she corrected all her measurements by subtracting 6 inches from each measurement. Later she wanted to convert her measurements to feet. That is, she uses the following formula: Corrected and converted measurement= (1/12) × (original measurement-6)= ((1/12) × original measurement) - 0.50. The corrected and converted measurements average feet with an SD of Fill in the blanks - or do you need the data? Explain briefly and/or show work. feet.
