(c) An epidemiologist is worried about the ever increasing trend of malaria in a certain locality and wants to estimate the proportion of people infected in the peak malaria transmission period. If he takes a random sample of 150 people in that locality during the peak transmission period and finds that 60 of them are positive for malaria, find i. 99% confidence interval for the proportion of the whole infected people in that locality during the peak malaria transmission period.
The population in this project hasa standard deviation that is unknown to us in principle, so the t-interval method that usesthe sample standard deviation, s, and t-values. Construct a confidence interval for theunknown population mean using the sample statistics. Sample mean: x=23.3 Sample size: n=30 Sample standard deviation: s=19.86 confidence level: 95%

Consider a situation in which sampling without replacement is used to generate a random sample from each of two separate populations. To calculate a confidence interval to estimate the difference between population proportions, which of the following checks must be made? * A) Both populations must be approximately normal. B) The data from both samples must be unimodal, symmetrical, and approximately normal. C) Each population must be at least 10 times as large as its corresponding sample. D) Each sample proportion value must be less than or equal to 0.5. E) The sample sizes must be the same.
The commute times for the workers in a city are normally distributed with an unknown population mean and standard deviation. If a random sample of 27 workers is taken and results in a sample mean of 22 minutes and sample deviation of 3 minutes, find a 95% confidence interval estimate for the population mean using the Student's t-distribution. df t0.10 t0.05 t0.025 t0.01 t0.005 ... ... ... ... ... ... 25 1.316 1.708 2.060 2.485 2.787 26 1.315 1.706 2.056 2.479 2.779 27 1.314 1.703 2.052 2.473 2.771 28 1.313 1.701 2.048 2.467 2.763
A district sales manager wishes to determine whether there is a difference in mean daily sales volume between two stores in his district. He collects daily sales volume for the month of June to do the analysis. Assume that the population standard deviations are unknown and unequal. The hypothesis test is to be conducted using the 0.01 level of significance. Partial output of his results from Excel can be found in the table below: Store 1 Store 2 Sample size (n) 30 30 Sample mean daily sales volume (in $1,000) 15 19 Sample standard deviation (in $1,000) 5.2 6.1 Degrees of freedom 56 What is the critical value of the test statistic?

Which of the following is the minimum sample size necessary to construct a 99% confidence interval for μ with a margin of error E = 0.05? Assume that the population variance is 0.25.
Assume that you have a sample of n1=8, with the sample mean x1=44, and a sample standard deviation of s1=5, and you have an independent sample of n2=14 from another population with a sample mean of x2=35, and the sample standard deviation s2=6. Construct a 95% confidence interval estimate of the population mean difference between m1 and m2. Assume the the two population variances are equal.

In the macro relation between GDP and FDI, Dr Mudenda obtained the following valuesfrom a Stata output: FDI coefficient of 0.45; t-statistic of 3; and covariance (GDP, FDI)value of 0.41. In literature, this relationship between GDP and FDI has generally beenestablished to be statistically significant. Answer the following questions:i) Calculate the variance of the FDI variable and explain its implicationii) Use the confidence interval approach to test whether FDI’s influence on GDP isstatically significant or not in Dr Mudenda’s study. Use 5% level which gives 1.96critical values.iii) What is the expected value of the p-values for studies that have been conductedin literature?
