Answer:
The standard deviation is not greater than 5 mg ()
Step-by-step explanation:
First we need to find the z-score for a 0.05 level of significance.
Looking in the z-table with alpha = 0.05, we have z = 1.645.
Now, finding the standard error of the mean, we have:
The standard deviation with 0.05 level of significance would be:
This deviation is not greater than 5 mg.
600 x 5 x i = 60
3000 i = 60
i = 60 / 3000
i = 0.02
0.02 = 2%

Answer:
A
Step-by-step explanation:
10^0 = 1
so 1*10^0 = 1*1 = 1m

or
32%
Step-by-step explanation:
Students must specialize in one style of dance.
Last summer there was 62 dancers.
20 of the 62 specialized in modern dance.
Therefore the probability of a random chosen dancer to be a modern specification is 20/62.
The answer is:
