in performing a chi-square goodness of fit test for a normal distribution, a researcher wants to make sure that all of the expected cell frequencies are at least five. the sample is divided into 7 intervals. thw seco d through the sixth intervals all have expected cell frequencies of at least five. the first and the last interval have expected cell frequencies of 1.5 each. after adjusting the number of intervals, the freedom for the chi-square statistic is

The chi-square goodness-of-fit test is used to determine whether observed frequencies significantly deviate from expected frequencies. In most instances, the researcher hopes to find a significant result (indicating that the observations deviate from expectations), which would provide some evidence for a treatment effect. • Share an example of a situation in which the researcher might hope for a non-significant result. Be sure to state why they would hope for such a result. (Type Answer & Explain your example)
