The price of a certain combo meal at different franchises of a national fast food company varies from $5.00 to $17.38 and has a known standard deviation of $2.13. A sample of 29 students in an online course that includes students across the country stated that their average price is $5.75. The students have also stated that they are generally unwilling to pay more than $6.50 for this meal. Formulate and conduct a hypothesis test to determine if you can conclude that the population mean is less than $6.50. Use a level of significance of 0.05. Is there sufficient evidence at the 0.05 level of significance that the population mean is less than $6.50? Determine the null hypothesis, Ho, and the alternative hypothesis, H, Ho: H 2 6.50 < 6.50 (Type integers or decimals. Do not round.) H,: H Compute the test statistic. - 1.90 (Round to two decimal places as needed.) Find the p-value for the test.

As a university instructor, charts are very useful to show statistical analysis of test scores to students. Students are always interested in how they scored compared to the whole class or where their score landed in the overall scheme of things. Which type of statistics would be most useful for comparisons? Which type of chart would be best to show the comparison of grades? How do charts help protect the privacy of individual grades?
Your task is to implement a class that provides methods ProcessTrade, Process PriceUpdate, OutputWorst rade. These method calls correspond to the instructions described above with the method arguments corresponding to the update or query attributes. Constraints • 1 ≤ N, Tradeld, Price, Volume ≤ 105 • It is guaranteed that price update for an instrument is available before first trade on that instrument. Input Format For Custom Testing Input to the program is specified using a simple text format. The format and details of parsing are not relevant to answering the question but custom input can be used to help with development and debugging. The first line of input contains an integer N that denotes the number of instructions. Each of the N subsequent lines contains either an update or a query in the format below: Updates: 4 TRADE . PRICE Query: . WORST TRADE Some example inputs and their expected outputs are described below.

Fordley Car Park is open between 7am and 9pm every day. They charge £2.30 per hour with a minimum fee of one hour and a £2 overnight charge for stays between 9pm and 7.30am. Payments are made at the end of a visit. The car park is also used by resident and business permit holders on the basis of annually renewable membership. All new memberships are registered via the Fordley Car Park website or by completing a form which can be picked up from the car park attendant. Recently Fordley has invested in a paperless attended smart parking system that scans car registration numbers as cars drive through the entrance gate. To ensure that a reading has been captured, the gates only open when a valid registration is read. Exit gates also have a camera which scans the car registration number and will open automatically unless payments are outstanding in which case the payment can be made at the attendant kiosk without leaving the car. Members whose membership has expired can also pay for the…
