Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 77.7 Mbps. The complete list of 50 data speeds has a mean of x= 18.55 Mbps and a standard deviation of s=31.38 Mbps. a. What is the difference between carrier's highest data speed and the mean of all 50 data speeds? b. How many standard deviations is that [the difference found in part (a))? c. Convert the carrier's highest data speed to a z score. d. If we consider data speeds that convert to z scores between - 2 and 2 to be neither significantly low nor significantly high, is the carrier's highest data speed significant? a. The difference is Mbps (Type an integer or a decimal. Do not round )

Suppose we want to know the mean number of shurikens thrown each night by ninjas in Konoha village. Getting this information from every ninja in the village would take forever. Instead, we randomly select 20 ninjas from the ninja school that is closest to us. a. Identify the population of interest in this survey b. Describe the parameter of interest in this survey. c. Identify the sample of interest in this survey.

4. A study was conducted to investigate the relationship between the size of a house (in square feet) and the selling price of a house (in dollars). The response variable is price in dollars, and we want to study if the covariate of the square footage helps explain the response. A random sample of 522 houses was used, and the linear regression output from R is below. price sqft, data = house) 1m (formula = Coefficients: Estimate Std.
