asicStats93.005.MI A random sample of 30 binomial equal 0.50. Use a level of significance of 0.05 trials resulted in 12 successes. Test the cdaim that the population proportion of successes does not (a) Can a normal distribution be used for the f distribution? Explain. O No, ng is greater than S, but np is less than 5 O No, np and ng are both less than 5 O No, np is greater than 5, but ng is less than S O Yes, np and ng are both greater than 5. O Yes, np and ng are both less than 5. (b) State the hypotheses. Compute the corresponding standardized sample test statistic. (Round your answer to two decimal places.) (d) Find the P.value of the test statistic. (Round your answer to four decimal places) (e) Do you reject or fail to reject Ho? Explain. At the ?-0.05 level, we reject the null hypothesis and codude the data re statsta?y sgrincant. O At the a 0.05 level, we reject the nul hypothesis and conclude the data are not statistically significant OAt the ?-0.05 level, we fail to reject the nin hypothesis and coolde the data are tatistically signeat O At the ?-OOS level, we fail to reject the nul hypothesis and codde the datare not statistically significant. O The sample f value based on 30 trials is sufficiently different from Q.50 to Justify rejecting Ho for a-0.05 O The sample ? value based on 30 trials is not sufficently different from 0.50 to Mthy rejecting M·for ?.OOS O The sampleß value based on 30 trials is sumoertly different ton, 0.50 to not reject n, for a-oos. O The sample f value based on 30 trials is not sufficiently dfferent from o.50 to not reject Ho for a- o.0s (1) What do the results tell you?Explanation / Answer
The statistical software output for this problem is:
One sample proportion summary hypothesis test:
p : Proportion of successes
H0 : p = 0.5
HA : p ? 0.5
Hypothesis test results:
Hence,
a) Option D is correct.
b) Option D is correct.
c) p = 0.40
Test statistic = -1.10
d) P - value = 0.2733
e) Option D is correct.
f) Option D is correct.
