In a sample of 35 houses in Fraggle Rock, the average size was 854 sqft with a standard deviation of 26 sqft. Construct a 95% confidence interval for the average square footage for a house in Fraggle Rock. On your scratch paper, answer parts 1 and 2. Round the square footage to one decimal place. Are the conditions met? Explain. Which critical value should you use, or ? Explain. With 95% confidence, the true average square footage is between [first] and [second] sqft.  

Which of the following is true of local display advertising?

Because video conferences make use of real-time and non-buffered video streaming, their videos must be encoded/decoded with variable bit rate (VBR).

The [1] layer and [2] layer of the Internet protocol stack are implemented in the end systems but not in the routers of the network core. You may write the name of these two layers in either order.

The weight of a Fraggle Rock Doozer is normally distributed with a mean of 282.3 grams and a standard deviation of 62.4 grams. A particular Doozer named Cotterpin is 184.3 grams. Find the z-score for Cotterpin’s weight, and the probability of randomly selecting a Doozer with a weight of at least 184.3 grams. Express your z-score to two decimal places and your probability to four decimal places. z-Score:  [zscore] Probability: [prob]  

Let z be the standard normal random variable. Find the following probabilities (or areas) to 4 decimal places.  1)  

In packet-switching networks, the packet suffers from several types of delays at each node along the path. The figure below indicates the four most important types of delays as introduced in the textbook that are accumulated to define a total nodal delay at router A. The four types of delays occur one after the other in the order from (a) to (d) as shown in the figure below, where (a) = [1] delay, (b) = [2] delay, (c) = [3] delay, and (d) = [4] delay, respectively.  

Which of the following is an inherent disadvantage of television advertising?

The height of a species native to Fraggle Rock, called Fraggles, are normally distributed with a height of 26.8 inches and a standard deviation of 1.4 inches. What is the probability that a sample of 5 Fraggles have an average weight more than 28 inches. Provide the z-score as well. Express your z-score to two decimal places and your probability to four decimal places. z-Score:  [zscore] Probability: [prob]
