The mean of \( n \) observations is \( \bar{X} \). If each observation is multiplied by \( \mathrm{k} \), the mean of new observations is a. \( \mathrm{k} \overline{\mathrm{X}} \) b. \( \frac{\bar{X}}{k} \) c. \( \overline{\mathrm{X}}-\mathrm{k} \) d. \( \bar{X}+k \) 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
