Question
Declare an interface Filter as follows:

public interface Filter { boolean accept(Object x); }

Modify the implementation of the Data class in Section 10.4 to use both a Measurer and a Filter object. Only objects that the filter accepts should be processed. Demonstrate your modification by processing a collection of bank accounts, filtering out all accounts with balances less than $1,000.

Solve Exercise •• P10.6, using a lambda expression for the filter.

How would you use a use a lambda expression for the filter class?????
below is working code for the first part of the question, thanks.

CRITAL THINKING:

1) Melanie, a breast cancer patient receiving chemotherapy, comes into your office for her normal treatment. Upon examination, it is revealed that Melanie is experiencing flulike symptoms. The physician asks you to order a CBC. What results might you expect for a patient with Melanie’s characteristics, and why? Why might Melanie be experiencing flulike symptoms?

need to write program on python, without using any other libraries like panda, numpy, etc.

here is google link on csv file https://drive.google.com/file/d/1O3cC9JAPVkXSrddTR6RocpSV8NMHrmRx/view?usp=sharing

There is a csv file, which is exel file, very big and what program should do:

- Read a CSV file 'annual.csv' enterprise into a data structure

- Count the number of rows and columns

- Determine if the data contains empty values (should search in all rows)

- Replace the empty values by 'NA' for strings, '0' for decimals and '0.0' for floats (in all rows)

- Transform all Upper case characters to Lower case characters (in every word)

- Transform all Lower case characters to Upper case characters (in every word in file)

- save back the 'repaired' array as csv and show edited version

- Print out the size of the data (number of rows, number of columns)

the file approzimately looks like this, but it is very huge

2.     The dataset QuizPulse10 contains pulse rates collected from 10 students in a class lecture and then from the same ten students during a quiz. We might expect the mean pulse rate to increase under the stress of a quiz. Use the dataset to test at the 5% significance level whether there is evidence to support this claim.

a.     Perform the hypothesis test in Minitab.

b.    Make a decision and mathematically justify your decision

c.     Interpret the results.

Problem 24-3A Departmental income statements; forecasts LO P3

Williams Company began operations in January 2017 with two operating (selling) departments and one service (office) department. Its departmental income statements follow.

Williams plans to open a third department in January 2018 that will sell paintings. Management predicts that the new department will generate $56,000 in sales with a 65% gross profit margin and will require the following direct expenses: sales salaries, $8,500; advertising, $1,100; store supplies, $1,000; and equipment depreciation, $900. It will fit the new department into the current rented space by taking some square footage from the other two departments. When opened, the new painting department will fill one-fifth of the space presently used by the clock department and one-fourth used by the mirror department. Management does not predict any increase in utilities costs, which are allocated to the departments in proportion to occupied space (or rent expense). The company allocates office department expenses to the operating departments in proportion to their sales. It expects the painting department to increase total office department expenses by $7,500. Since the painting department will bring new customers into the store, management expects sales in both the clock and mirror departments to increase by 11%. No changes for those departments’ gross profit percents or their direct expenses are expected except for store supplies used, which will increase in proportion to sales.

Required:
Prepare departmental income statements that show the company’s predicted results of operations for calendar-year 2018 for the three operating (selling) departments and their combined totals. (Do not round intermediate calculations. Round your final answers to nearest whole dollar amount.

Smart sensor nodes can process data collected from sensors, make decisions, and recognize relevant events based on the sensed information before sharing it with other nodes. In wireless sensor networks, the smart sensor nodes are usually grouped in clusters for effective cooperation. One sensor node in each cluster must act as a cluster head. The cluster head depletes its energy resources faster than the other nodes. Thus, the cluster-head role must be periodically reassigned (rotated) to different sensor nodes to achieve a long lifetime of wireless sensor network. Discuss in detail what are the major attributes required for choosing the optimal cluster head and explain how the choosing of optimal cluster head helps in
extending the lifetime of the wireless sensor networks, rotating the cluster-head role among sensor nodes with suppression of unnecessary data transmissions. ()

A certain advertising company has commissioned a study to determine if a recent advertising campaign is effective for certain age groups. Researchers have created a data file (results.txt) which contains the results attained by the study. The first column is the subject’s name (you may assume there is no whitespace in any name) and the second column indicates if the subject has seen the advertisement in question (Y or y means yes, N or n means no). The third column specifies the subject's age and the last column (the 'score') specifies how favorably the subject views the product being advertised (from 0 to 100 with a score of 100 being most favorable). A example of the file results.txt is attached. You should download this file to a convenient place on your hard drive. Please note that the file is a sample only. Your program should work on any data file that is formatted in a similar way.

Your assignment is to prompt the user to enter the full pathname to the data file on disk. If the file does not exist in the specified location, your program should exit with a suitable error message.

The first thing your program should do is output to the screen a copy of the data read in from the disk file. This is known as “echoing” the input data. Your program should then calculate and display the the following results:

 Average score for subjects under 18 who have not seen the ad.

 Average score for subjects under 18 who have seen the ad.

 Average score for subjects 18 to 35 (inclusive) who have not seen the ad.

 Average score for subjects 18 to 35 (inclusive) who have seen the ad.

 Average score for subjects over 35 who have not seen the ad.

 Average score for subjects over 35 who have seen the ad.

Display your results to two places of decimals, and write your program to automatically list your six calculated averages one to a line, in the order above, along with a suitable label for each result.

Finally, your program should calculate and display to two places of decimals the overall average score for all of the subjects surveyed. (Note: Mathematically, this is NOT the average of the six averages you calculated previously).

Warning: There may be no subjects in any given category (such as over 35s who have not seen the ad). If so you cannot calculate the average (because you would get a divide by zero error) so instead of the average for that category you should display “No data to report”.
