Amanufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 420.0420.0 gram setting. it is believed that the machine is underfilling the bags. a bag sample had a mean of 417.0417.0 grams. a level of significance of 0.010.01 will be used. state the hypotheses. assume the variance is known to be 576.00576.00. enter the hypotheses:

What properties allow transformation to be used as a problem solving tool

Someone answer asap for ! max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a. the median of max’s data is 250 b. more than half of the data points max recorded were 177 centimeters. c. a data point chosen at random is as likely to be above the mean as it is to be below the mean. d. every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.

I’m still confused on how to work the percentages
