Problem 8CRE

Stemplot of Grooming Times Use the data from Exercise to construct a stemplot.

Exercise

Grooming Time Listed below are times (minutes) spent on hygiene and grooming in the morning (by randomly selected subjects) (based on data from a Svenska Cellulosa Aktiebolaget survey). Construct a table representing the frequency distribution. Use the classes 0–9, 10–19, and so on.

Answer :

Step 1 of 1 :

Grooming Time Listed below are times (minutes) spent on hygiene and grooming in the morning (by randomly selected subjects) (based on data from a Svenska Cellulosa Aktiebolaget survey).

0, 05,12,15,15,20,22,24,25,25,25,27,27,28,30,30,35,35,40,45

Now we have to construct a stemplot of these values.

0, 05,12,15,15,20,22,24,25,25,25,27,27,28,30,30,35,35,40,45

We consider.

0, 05

Here stem = 0 and leaf 0 5

Then we consider

12,15,15

Here stem = 1 and leaf 2 5 5

Then the stem and leaf table is given below.

Stem |
Leaf |

0 |
0 5 |

1 |
2 5 5 |

2 |
0 2 4 5 5 5 7 7 8 |

3 |
0 0 5 5 |

4 |
0 5 |
