Question 1
A. In a sample from an approximately normal distribution we find the following values:
444 421 441 460 439 448 451 .
The order of magnitude of the sample standard deviation is:
1) 1
2) 10
3) 100
4) 1000
5) 10000
6) 100000
7) 1000000 or more
B. Based on a sample of size n a researcher has made the following box-arid whisker

Box-and-whiskcrPlot
For the sample distribution of these data we state:

2) the distribution is left-skewed.
3) the distribution is symmetrical.
4) there is not enough information to evaluate the shape of this distribution.
