tely 10,000 records in 2017 and 9,000 records in 2018. I am trying to assess whether there was an increase in salaries between the years.
My Lternative hypothesis is the records greater than 2016, and my null hypothesis is any records equal to or less than 2017.
How do I calculate the data?

In a game of chance player spin the pointer of a spinner with six equal-sized sections. part A what is the sample space of the g
oksano4ka [1.4K]

Answer:

The sample space of the game is: S = {1, 2, 3, 4, 5, 6}.

Step-by-step explanation:

Sample space is a set of all possible outcomes of an experiment.

Consider a few example:

  • Consider the experiment of tossing a coin. The sample space of this experiment consists of only two outcomes, i.e. Heads (H) and Tails (T).
  • Consider the experiment of rolling a fair six-sided die. The sample space of this experiment consists of six outcomes, i.e. faces 1, 2, 3, 4, 5 and 6.
  • Consider the experiment of selecting a card from a pack of 52 cards. The sample space of this experiment consists of 52 distinct outcomes.

The probability of all the outcomes in a sample space always sum up to 1.

Thus, fulfilling the condition of a valid sample space.

In this case, a game is played by spinning a pointer of a spinner with six equal-sized sections.

So, the pointer has 6 possible sections to land.

The pointer lands on any of the 6 sections with same probability, i.e. \frac{1}{6}.

The sample space of the experiment is:

S = {1, 2, 3, 4, 5, 6}
