A random sample of 130 observations is selected from a binomial population with unknown probability of success p. The computed value of p is 0.64.(1) Test Ho: p-0.6 against H, :p> 0.6 Use a =0.05test statistic zcritical z scoreThe final conclusion isOA. There is not sufficient evidence to reject the null hypothesis that p= 0.6OB. We can reject the null hypothesis that p=0.6 and accept that p > 0.6.(2) Test Ho: p-0.5 against H, p<0.5 Use a-test statistic -critical z scoreThe final conclusion isOA. There is not sufficient evidence to reject the null hypothesis that p=0.5B. We can reject the null hypothesis that p-0.5 and accept that p < 0.5(3) Test Ho: p-0.6 against H.: p0.6 Use a- 0.05test statistic zpositive entical z score0.05negative critical scoreThe final conclusion isOA. We can reject the null hypothesis that p=0.6 and accept that p0.6.B. There is not sufficient evidence to reject the null hypothesis that p-0.6.

A random sample of n = 1,400 observations from a binomial population produced x = 388. (a) If your research hypothesis is that p differs from 0.3, what hypotheses should you test? Ho: p 0.3 Ho: p = 0.3 versus H₂: p = 0.3 Ho: p = 0.3 versus H₂: p 0.3 Ho: p = 0.3 versus H₂: p = 0.3 (b) Calculate the test statistic and its p-value. (Round your test statistic to two decimal places and your p-value to four decimal places.) Z = p-value = Use the p-value to evaluate the statistical significance of the results at the 1% level. Ho is rejected since the p-value is not less than 0.01. Ho is rejected since the p-value is less than 0.01. Ho is not rejected since the p-value is not less than 0.01. Ho is not rejected since the p-value is less than 0.01. (c) Do the data provide sufficient evidence to indicate that p is different from 0.3? Yes, the data provide sufficient evidence to indicate that p is different from 0.3. No, the data do not provide sufficient evidence to indicate that p is different…
19 of 30 Ne II I have a dataset that lists the level of two blood proteins for each individual in a group of 100 people. My hypothesis is that the level of the first of these proteins depends on the level of the second protein. Assuming the levels of both proteins are Normally distributed, which of the following tests should I use to assess my hypothesis? 1-way ANOVA Paired, 2-tailed t-test O Spearman correlation Pearson correlation Unpaired, 2-tailed t-test

Suppose a sample size of 87 was used to conduct a right tailed hypothesis test for a single population mean. The null |hypothesis was Ho: µ 45 and the sample mean was 50 and the p-value was 0.03. Then there is a 3% chance that 87 randomly selected individuals from a population with a mean of 45 and the same standard deviation would have a sample mean greater than 50. false true

In many situations in which the ifrene n variances i not to great the esuts from the AOV comparisons of the population means of the ransformed data are very similar to the resuts hat would have been obtained using the original data.In thesestuation,the researcheris inclined to ignore the ransformations because the scale of the transformed data is not relevant to the researcher. Thus, confidence intervals constructed for the means using the transformed data may not be very relevant. One possible remedyfor this problem is to construct confidence intervals using the transformed data and then perform an inverse transformation of the endpoints of the intervals. Then we would obtain a confidence interal with values having the same units of measurement as the original data. Subject A, A A
