The speeds of 57 cars were measured (in km/h) on a city street. A numerical summary of the results is given below:   Descriptive Statistics: speed   Variable      N      N*       Mean        SE Mean        StDev speed           57      0          45.53         1.64                 12.38   Variable         Minimum       Q1           Median       Q3              Maximum speed               25.60               35.00       43.20            55.00        83.20   Do a calculation to decide whether the lowest recorded speed, 25.60 km/h, would be a potential outlier if drawing a boxplot by hand for this data set. What do you conclude?

For a standard deck of cards, calculate the following probabilities. Exclude jokers. Be sure to show some intermediate work.   a) p (a red card or a jack) b) p (a diamond, given that 3 spades, 4 hearts, 2 clubs, and 3 diamond already were drawn)

In relational model terminology, table is considered as

Early language models could predict the probability of a single word; modern large language models (LLMs) can predict the probability of:

What is the main difference between a flipped classroom and traditional teaching methods?

Explain the concept of blended learning and how the flipped classroom model fits within it.

In a flipped classroom, students first engage with new material , usually through video lectures or reading assignments, and then use classroom time to deepen their understanding through interactive activities, discussions, and problem-solving exercises facilitated by the instructor.
