Most communication developers claim that a 5G+ wireless connection would give an averagespectral efficiency of exactly 30 bps/Hz. To test the claim, a spectral efficiency performancefrom a random sample of MIMO technologies in bps/Hz has been obtained below:30.529.630.230.62931.629.131.630.930.930.729.229.230.830.630.330.53029.830.932.730.330.33030.831.730.62932.529.829.331.930.930.329.3Using the sample data above, show and compute the point estimate of the true average spectralefficiency. Next, test whether the claim is true at the 98.5% confidence level. Finally, repeat thetest using the p-value approach at the 98.5% confidence level.

The margin of error is the maximum expected difference between the estimate of the population characteristic and the actual population characteristic. Each of the sample proportions are good estimates of the population proportion, so we should give a margin of error that contains about 95% of the sample proportions to be reasonably sure that the actual population proportion is in the range between the mean minus the margin of error to the mean plus the margin of error. What margin of error should be given along with the estimate of…
A major credit card company is investigating whether the distribution of the number of credit cards used by its customers has changed from last year to this year. Customers are classified as using 1 card, 2 cards, or more than 2 cards. The company conducts a chi-square goodness-of-fit test to investigate whether there is a change in the distribution of number of cards used from last year to this year. The value of the chi-square test statistic was χ2=7.82 with a corresponding p-value of 0.02. Assuming the conditions for inference were met, which of the following is the correct interpretation of this p-value? There is a 2 percent chance that the company’s claim is correct. A There is a 2 percent chance of obtaining a chi-square value of at least 7.82. B If the null hypothesis were true, there is a 2 percent chance of obtaining a chi-square value of at least 7.82. C If the null hypothesis were true, there is a 2 percent chance that the company’s claim is…
A researcher was interested whether an individual's preference in political party affiliation was influenced by their level of education and gender. A random sample of participants were recruited, and preferences were scored from 0 - 10 (0 meaning no preference, 10 meaning greater preference). The researcher then divided participants by gender (1 = male/2 = female) and then again by level of education (1 = some school/2 = college/3 = university). Assume alpha at 0.05. Gender Education Level Political Interest 1 10 1 1 9. 1 2 2 1 1 1 1 1 1 4 4 1 9. 1 3 8 What is the dependent variable? What is the appropriate type of statistical analysis to run?

A graduate-level computer science course only gives the grades of A, B, or C. The department has determined that there should be 40% A's given, 40% B's given and 20% C's given as final grades for the course. For the spring 2021 semester, 200 students took the course and 100 students received A's, 50 students received B's and 50 students received C's, so those are my observed frequencies. We want to do a Chi-square Multinomial Goodness of Fit test to see if our grading guidelines match up with what is actually happening. What is the expected frequency for the grade of B category? Round your answer to the tenths position.

Suppose that having a widow's peak was a dominant trait (W) compared to not having a widow's peak (w). In a sample size of 30 students, 15 were observed to have a widow's peak and 15 did not have a widow's peak. The expected frequency of a widow's peak is 75% chance of getting it and a 25% chance of not getting it. Perform a chi square analysis to see if the data above agrees with the predicted outcome.
