Solving first 4 as per HOMEWORKLIB POLICY. Please post rest in a separate question. Thank you.

**A.** Sample mean would be the total movies watched/25

=0*3+1*4+2*3+3*8+4*7/25

=0+4+6+24+28/25

=62/25

=**2.48**

**B.** Standard deviation of a population is given by

where mu is mean of the population, N is the number of populatio. Putting values in and calculating, we get

standard deviation=**1.36**

**C.** The histogram has been created below

**D.**

The table has been filled below. Explanation follows

No of movies | Frequency | Relative Frequency | Cumulative Relative Frequency |

0 | 3 | 0.12 | 0.12 |

1 | 4 | 0.16 | 0.28 |

2 | 3 | 0.12 | 0.4 |

3 | 8 | 0.32 | 0.72 |

4 | 7 | 0.28 | 1 |

Relative frequency=frequency of current number/total frequency (which is 25 in our case)

Cumulative Relative Frequency=sum of all relative frequencies till that number.

- ΗΣΟι – μ)

Frequency 3 1 2 3 No of movies watched
