Normal Distributions. Answer the given questions which are related to normal distributions.

Normal Distribution Refer to the frequency distribution given in Exercise 9 and ignore the given frequencies. Assume that the first two frequencies are 4 and 7, respectively. Assuming that the distribution of the 40 sample values is a normal distribution, identify the remaining three frequencies.

Exercise 9

Problem 13BSC

Answer:

Step1 of 3:

We have Refer to the frequency distribution given in Exercise 9 and ignore the given frequencies. Assume that the first two frequencies are 4 and 7, respectively. Assuming that the distribution of the 40 sample values is a normal distribution.

CI | frequency |

3.0-4.9 | 8 |

5.0-6.9 | 15 |

7.0-8.9 | 11 |

9.0-10.9 | 5 |

11.0-12.9 | 1 |
