Directions: 1Write a report of your answers on separate sheets of paper, taking care to prepare a legible and organized report. Put your name on your report. Answer questions in order and underline or draw a box around any nal numerical answers. Show your work for all answers and include the company name you obtained the data from. Full credit will not be given to answers without work, and partial credit may be given when work is shown. Write any written answers or explanations clearly, and be as neat as possible. You will have to submit your assignment on Canvas as a mist tile (single le pleasel). You can embed pictures of your homework in a Word le and save it as pdf. Pro tip: use a scanning app such as \"CamScarmer.\" It's ee and it will produce quality pdf les. Notes on iPhones also a allows you to scan documents and save to pdf. 1. You will need the same dataset used for problem 3 in homework I (the dataset obtained 'om the yahoo website with the company you selected}. Use Excel to calculate the average and standard deviation of the close data column. Assume that these two numbers represent the population {=parametric} mean and population standard deviation, respectively, for the variable length {in cm) in a population of a species of sh. Attach a printout of the data to your homework and write down the ticker code ou it. 3. Calculate the probability of sampling at random a sh that is smaller in size than the value you would obtain by subtracting halfthe standard deviation from the average [a will be equal to: p. (o b. Calculate the probability of sampling at random a sh that is greater in size than the value you would obtain by adding halfthe standard deviation orn the average [x = p. + (#2)] c. Calculate the probability of sampling at random a sh that has a size between the two values [a = p ((#2), x = p. + (5152)] used in parts \"a" and "b,\" respectively {1. Calculate the 25th and T5111 percentiles of sh size for the population using the normal distribution table. e. Imagine that 5 individuals are sampled at random from this fish population. Calculate the probability that the average calculated will be less than the value: H - (6/3) NOTE: Assume the variable is normally distributed and use bell-shaped curve diagrams to shade the areas that correspond with the answers to questions "a" through "d"2. Write the last two digits of your l student ID number with a decimal point in between these two digits: Assume that this number is the average number of squirrels you come across when you walk from the Life Science Building {L5} to the Engineering Research Building (ERR). Tomorrow you plan to walk from L5 to ERB and you wonder what it the probability of observing at most three squirrels. Assume that squirrels are randomly distributed and that each squirrel is an independent observation. NOTE: if your last two digits happen to be both I}, use 4.2 as the average number of squirrels encountered. 3. Write the last digit of your 1000 student ID number: _ You know that in a specic population of rainbow trout 15% of the individuals carry intestinal parasites. Assume you obtain a random sample of 9 individuals 'om this population: a. Calculate the probability that _ (last digit of your ID number} carry intestinal parasites. b. Calculate the probability that at least two individuals carry intestinal parasites. NOTE: you can still calculate \"a\" if your last digit is \"ll.\" PROBLEM 1: PROBLEM 2: No. of Relative Cumulative Relative Cumulative Calls Frequency Frequency Frequency Rewrite the given data vertically in a column of a table.

Frequency 7- 142.70 2 3 5 = 14. 27 Number of Courtship Calls The data tell us that we have a sample of 10 biology students. We can use the formula below to calculate the standard deviation. The graph above compares the frequencies of the courtship calls made by Male purple dart-poison frogs during the afternoon. 5 is the mode or the most common number of courtship calls with 7 times, followed by 6. 4, 3. and others. "-1 The frequencies run from 1 to 8, giving a range of 7. Moreover, the frequencies look like a bell-shape, suggesting that the distribution of frequencies is normal among the number of courtship calls. 14.26 10 - 1 = 1.26 Therefore, the standard deviation of the blood glucose levels for ten biology students is 1.26 millimoles per liter.
