I need help with this question please 

A distribution and the observed frequencies of the values of a variable from a simple random sample of the population are provided below. Use the chi-square goodness-of-fit test to decide, at the specified significance level, whether the distribution of the variable differs from the given distribution. Distribution: 0.125, 0.25, 0.25, 0.375 Observed frequencies: 18, 22, 24, 32 Significance level = 0.05 Compute the value of the test statistic, y. 2 =855 (Round to three decimal places as needed.) Find the P-value. Choose the correct answer below. O A. 0.025<P<0.05 O B. P<0.005 OC. 0.05 <P<0.10 D. P>0.10 O E. 0.005 <P<0.01 O F. 0.01 <P<0.025 Does the data provide sufficient evidence that the distribution of the variable differs from the given distribution? O A.
