Question

2. A political scientist believes that, in recent years, the ethnic composition of the city in which he lives has changed. The most current figures (collected a few years ago) show that the inhabitants were 53\% Norwegian, 32\% Swedish, 8\% Irish, 5\% Hispanic, and 2\% Italian. To test his belief, a random sample of 750 inhabitants is taken. Of the 750 participants, 399 were Norwegian, 193 were Swedish, 63 were Irish, 82 were Hispanic, and 13 were Italian. Using \( \alpha= \) 0.05 , what can the scientist conclude? \( \mathrm{H}_{0} \) : \( \qquad \) \( \mathrm{H}_{1} \) : \( \qquad \) df (if appropriate): \( \qquad \) Critical value: \( \qquad \) State Results, Decision, and Conclusions:
