A packaging process has a problem of producing underweighted packages. A package is considered to be underweighted if its weight is below 20 ounces. To inspect the weights, the quality inspector randomly selects 4 packages as a batch and then weighs each package. The data from the inspection is shown below. Weight Package 1 Package 2 Package 3 Package 4 Batch 1 23 22 12 11 Batch 2 24 19 25 17 Batch 3 24 24 26 24 Batch 4 18 20.5 24 14 Batch 5 20 19 21 26 The inspector constructs a control chart for monitoring the number of underweighted packages per batch. Calculate Upper Control Limit (UCL) of the chart for the confidence level 98%. Note: Round only your final answer to 2 decimal places
