Define the sample space and the type for the sample space for the following cases. To get simpler expressions, you can prefer the set notation if needed. For questions requiring a plot, provide the sample space by using Cartesian Coordinate system. (a) My computer mouse needs a battery to function. I buy a battery and it lasts X amount of time. Then I install a new battery into the mouse. If Y represents the time that the mouse is ON,...

Using the data set, construct a histogram of the sales data. Is the data set unimodal or multimodal? Is the dataset left skewed, right skewed, or symmetric?

For each of the following questions carefully define (1) the sample space and (2) the event under consideration. Then (3) determine the probability. For full credit, you will have to display these three parts. We are given six cards: Two of the cards are black and they are numbered 1, 2; and the other four cards are red and they are numbered 1, 2, 3, 4. We pick two cards at the same time. What is the probability that both...

The TEST grade of a statistics class has a skewed distribution with mean of 79 and standard deviation of 8.2. If a random sample of 35 students selected from this class, then what is the probability that average TEST grade of this sample is between 76 and 82? Answer: (round to 4 decimal places) The average amount of water in randomly selected 16-ounce bottles of water is 15.87 ounces with a standard deviation of 0.55 ounces. If a random sample...

For each of the following, determine whether the distribution described is more likely skewed right, skewed left, or relatively symmetric.

For each of the following, determine whether the distribution described is more likely skewed right, skewed left, or relatively symmetric.Number of sick days in the GC student populationSalaries for all players in the NFLNumber of cars owned per American citizenHeights of all females in the GC population

For each of the following, state whether you expect the distribution to be symmetric, right skewed,...

For each of the following, state whether you expect the distribution to be symmetric, right skewed, or left skewed. Also specify whether the mean or median would best represent a typical observation in the data, and whether the variability of observations would be best represented using the standard deviation or IQR. Explain your reasoning. -Housing prices in a country where 25% of the houses cost below $350,000, 50% of the houses cost below $450,000, 75% of the houses cost below...

he final exam grade of a statistics class has a skewed distribution with mean of 78 and standard deviation of 7.8. If a random sample of 30 students selected from this class, then what is the probability that average final exam grade of this sample is between 75 and 80?

In Statistics, a histogram is a graphical representation of data using bars of different heights. In a histogram, each bar groups numbers into ranges. Taller bars show that more data falls in that range. A histogram displays the shape and spread of continuous or discrete sample data. In this project, you will write a program that creates a histogram that allows users to visually inspect the frequency distribution of a set of values. REQUIREMENTS: * Read from the data file...
