Heights​ (cm) and weights​ (kg) are measured for 100 randomly selected adult​ males, and range from heights of 134to 192 cm and weights of 37 to 150 kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield x=167.91 cm, y=81.34 kg, r=0.408​, P value=0.000​, and y=−103+1.06x. Find the best predicted value of y (weight) given an adult male who is 179 cm tall. Use a 0.01 significance level. The best predicted value of y for an adult male who is 179 cm tall is _____? kg.

A product is designed to have length of 29cm+/0.0.238cm. the output of the manufacturing process is identified to be centered at 29.0.0016cm and the standard deviation is estimated at 0.07cm. determine the capability of the system Cpk

A population has a mean of u = 50 and a standard deviation of a = 10. If 3 points were added to every score in the population, what would be the new values for the mean and standard deviation? O The new mean is u = 47, and the new standard deviation is a = 13. The new mean is u = 47, and the standard deviation is still a = 10. O The new mean is u = 53, and the standard deviation is still o = 10. O The mean is still u = 50, and the new standard deviation is a = 13. If every score in the population were multiplied by 2, what would be the new values for the mean and standard deviation? The new mean is µ = 100, and the new standard deviation is still a = 10. The new mean is u = 52, and the new standard deviation is o = 20. The new mean is u = 100, and the new standard deviation is a = 20. The mean is still u = 50, and the new standard deviation is o = 20.

A sample of n=25 scores has a mean of M=68. Find the z-score for this sample: if it was obtained from a population with u=60 and 0=10
