Constructing Normal Quantité Plots. In Exercises, use the given data values to identify the corresponding z scores that are used for a normal quantile plot, then identify the coordinates of each point in the normal quantile plot. Construct the normal quantile plot, then determine whether the data appear to be from a population with a normal distribution.

Braking Distances A sample of braking distances (in feet) measured under standard conditions for a sample of large cars from Data Set 14: 139, 134, 145, 143, 131.

Answer :

Step 1 of 1 :

Given Braking Distances A sample of braking distances (in feet) measured under standard conditions for a sample of large cars from Data Set 14:

139, 134, 145, 143, 131.

First sort the data by arranging the values in order from lowest to highest.

131,134,139,143,145

x-values |

131 |

134 |

139 |

143 |

145 |

Here n = 5

Then we have to identify the cumulative areas to the left of the corresponding values.
