(d) Ho: The distribution of favorite ice cream for customers at her shop is not same as it is for Amercians in general.

(e) Test statistics

Data | Observed values (fo) | Expected Proportions | Expected values (fe) | (fo-fe)2/ fe |

vanilla | 210 | 0.236 | 228.92 | 1.564 |

chocolate | 219 | 0.238 | 230.86 | 0.609 |

Total | 970 | 1.000 | 970.00 | 5.487 |

= 5.487

(f) p value = 0.2409

(g) p value is greater than alpha

(h) Based on this, we should not reject null hypothesis. (fail to reject Ho)

(i) There is insufficient evidence to conclude that the distribution of fav ice cream for customer in her shop is not the smae as it is for Americans in general.
