Using the mongoimport tool, load the database "companies" with documents found in the "companies. json" file into the "research" collection. verify your load by issuing the following queries: a. db. research. find({"name" : "adventnet"}) b. db. research. find({"founded_year" : 1996},{"name" : 1}).limit(10) provide screenshots of the results as evidence

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. the highest speed measured was 78.1 mbps. the complete list of 50 data speeds has a mean of x overbarequals16.11 mbps and a standard deviation of sequals18.65 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 minus2 and 2 to be neither significantly low nor significantly high, is the carrier's highest data speed significant? a. the difference is nothing mbps.
