Question

Assume that weights of adult females are normally distributed with a mean of 78 kg and a standard deviation of 21 kg. What percentage of individual adult females have weights less than 83 kg? If samples of 49 adult females are randomly selected and the mean weight is computed for each sample, what percentage of the sample means are less than 83 kg?

The percentage of individual adult females with weights less than 83 kg is ___%.

The percentage of samples of 36 adult females with mean weights less than 83 kg is ____%.

A. Find the probability that an individual distance is greater
than 214.80cm
b.find the probability that the mean 25 randomly selected
distances is greater than 203.70
c. why

The overhead reach distances of adult females are normally
distributed with a mean of 200 cm. and a standard deviation of 8
cm.
Find the probability that an individual’s distance is less than
205cm.
Find the probability that the mean for 25 randomly selected
distances is less than 205cm.

The overhead reach distances of adult females are normally
distributed with a mean of 197.5 and a standard deviation of 8.9
cm.
a. Find the probability that an individual distance is greater
than 206.80 cm.
b. Find the probability that the mean for 15 randomly selected
distances is greater than 195.30
c. Why can the normal distribution be used in part (b), even
though the sample size does not exceed 30?

The overhead reach distances of adult females are normally
distributed with a mean of 197.5 and a standard deviation of 8.9
cm. a. Find the probability that an individual distance is greater
than 210.90 cm. b. Find the probability that the mean for 15
randomly selected distances is greater than 195.30 cm. c. Why can
the normal distribution be used in part (b), even though the
sample size does not exceed 30? a. The probability is

assume that females have pulse rates that are normally distributed
