Question

The age distribution of the Canadian population and the age distribution of a random sample of 455 residents in the Indian community of a village are shown below.

Age (years) |
Percent of Canadian Population |
Observed Numberin the Village |

Under 5 | 7.2% | 50 |

5 to 14 | 13.6% | 69 |

15 to 64 | 67.1% | 289 |

65 and older | 12.1% | 47 |

Use a 5% level of significance to test the claim that the age distribution of the general Canadian population fits the age distribution of the residents of Red Lake Village.

(a) Find the value of the chi-square statistic for the sample. (Round your answer to three decimal places.)

(b) Estimate the *P*-value of the sample test
statistic.

*P*-value > 0.100

0.050 < *P*-value <
0.100

0.025 < *P*-value < 0.050

0.010 < *P*-value < 0.025

0.005 < *P*-value < 0.010

*P*-value < 0.005

(c) Based on your answers in parts (a) to (c), will you reject or
fail to reject the null hypothesis that the population fits the
specified distribution of categories?

Since the *P*-value > α, we fail to reject the null
hypothesis.

Since the *P*-value > α, we reject the null
hypothesis.

Since the *P*-value ≤ α, we reject the null
hypothesis.

Since the *P*-value ≤ α, we fail to reject the null
hypothesis.

Answer #1

this is chi-square goodness of fit test

a)

TS = 11.941

b)

p-value = 0.0076

0.005 < *P*-value < 0.010

c)

Since the *P*-value ≤ α, we reject the null
hypothesis.
