According to a recent article about individuals who have credit cards, the mean number of cards per person with credit cards is 4.5. To test this result a random survey of 60 individualswho have credit cards was conducted. The survey only includes the number of credit cards per participant. The results of the survey are attached below.(a) What is the variable of interest in this study? Is it qualitative or quantitative?(b) Do the results of the survey imply that the mean number of cards per individual is less than 4.5?

An investor wants to know if the average value of property is different from PKR 85000/=. He made a sample of different values of that property from different estate agents. Accordingly, the provided property values are PKR 62000/=, PKR 67000/=, PKR 75000, PKR 88000/=, PKR 83000/= and PKR 95000/=. Can the investor have 95 percent confidence that the mean value for the property on the test would be different from PKR 85000/=?

HBL Bank Pvt LtD. is studying its ATM use in the Gulshan-e-Iqbal area of Karachi. A sample of 30 ATMs showed they were used in the given number of times (in seconds) on a particular day, as shown in Table 1. Identify the presence of outliers in this dataset After removing the outliers (if present) from the given dataset, what is the expected or average number of times (in seconds) the ATM is used in the new dataset (if outliers were detected and removed). Show your results with errors in the statistical expected or average value. 83.24 64.01 84.23 76.20 84.21 54.29 5.11 59.21 70.23 61.01 63.10 80.23 84.21 73.20 68.11 52.19 65.22 90.16 52.16 177.21 95.23 36.15 48.12 16.18 59.32 84.22 195.13 47.18 87.13 26.11
You are the manager of a restaurant for a fast-food franchise. Last month, the mean waiting time at the drive-through window for branches in your geographical region, as measured from the time a customer places an order until the time the customer receives the order, was 3.9 minutes. You select a random sample of 64 orders. The sample mean waiting time is 3.61 minutes, with a sample standard deviation of 0.8 minute. a) At the 0.05 level of significance, is there evidence that the population mean waiting time is different from 3.9 minutes? State the null and alternative hypotheses. H0: H1: (Type integers or decimals.)
