Question

In an experiment, subjects tasted a mixture of salt and sucrose. Here are numbers that represent how salty each subject judged the concentration to be:

13.5	21.8	28.4	36.1	48.1	48.6
51.4	53.8	59.9	68.0	79.1	103.1

1. Use technology to make a histogram and include your graph.
2. Describe your histogram.
3. Compute the mean and standard deviation.

Answer 1

a)

b)

This histogram shows the concentration of salt vs the frequency of it.

The X-axis shows the concentration whereas Y-axis shows the frequency of it.

c)

Mean	50.98333	AVERAGE(M5: M16)
S.D	25.02009	STDEV.S(M5: M16)
