Question
Are all the expected frequencies greater than 57
O Yes
O No
What sampling distribution will you use?
uniform
O Student'st
O binomial
O normal
O chi-square
What are the degrees of freedom?
(c) Estimate the P-value of the sample test statistic.
P-value > 0.100
O 0.050 < P-value <0.100
0.025 < P-value < 0.050
O 0.010 < P-value <0.025
0.005 < P-value < 0.010
OP-value < 0.005
(d) 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?
O since the P-value > a, we fail to reject the null hypothesis.
since the Pvalue> a, we reject the null hypothesis.
O Since the P-value sa, we reject the null hypothesis.
Since the P-value sa, we fail to reject the nul hypothesis.
