Listed below are the top 10 annual salaries​ (in millions of​ dollars) of TV personalities. Find the​ range, variance, and standard deviation for the sample data. Given that these are the top 10​ salaries, do we know anything about the variation of salaries of TV personalities in​ general? 39 38 37 30 21 18 17 15 14.6 13.2
The range of the sample data is ​$___ million. ​(Type an integer or a​ decimal.)

The variance of the sample data is
nothing. ​(Round to two decimal places as​ needed.)

The standard deviation of the sample data is ​$
nothing million.
​(Round to two decimal places as​ needed.)
Is the standard deviation of the sample a good estimate of the variation of salaries of TV personalities in​ general?
A. ​No, because there is an outlier in the sample data.
B. ​Yes, because the standard deviation is an unbiased estimator.
C. ​Yes, because the sample is random.
D. No, because the sample is not representative of the whole population.

Ling listed all of the factors of a mystery number: 1,2,4,8,16,32 what is the mystery number?

Amachine that produces a special type of transistor (a component of computers) has a 2% defective rate. the production is considered a random process where each transistor is independent of the others. (a) what is the probability that the 10th transistor produced is the first with a defect? (b) what is the probability that the machine produces no defective transistors in a batch of 100? (c) on average, how many transistors would you expect to be produced before the first with a defect? what is the standard deviation? (d) another machine that also produces transistors has a 5% defective rate where each transistor is produced independent of the others. on average how many transistors would you expect to be produced with this machine before the first with a defect? what is the standard deviation? (e) based on your answers to parts (c) and (d), how does increasing the probability of an event a↵ect the mean and standard deviation of the wait time until success?

This assignment is past the original due date o this data is from a sample. calculate the mean, standard deviation, and variance 16.7 11.1 46.7 14.8 13.3 16.6 18.5 47.3 42,8 show the following answers to 2 decimal places. sample mean- sample standard deviation ( use the standard deviation above for your calculation.) sample variance ooops- now you discover that the data was actually from a population! so now you must give the population standard deviation.
