Answer:The Mann-Whitney U test is used to compare differences between two independent groups when the dependent variable is either ordinal or continuous, but not normally distributed. ... The Mann-Whitney U test is often considered the nonparametric alternative to the independent t-test although this is not always the case.

For #6;

We know that there are 46% male students and 30% of them are seniors. This means that we have to assume that 30% of the male students are seniors and that 30% of the female students are seniors. Taking 30% of 46% gives us 13.8%.

For #7;

We are looking for the possibility that we choose a junior student (22%) or a sophomore student (28%). This adds up to 50% (22%+28% = 50%). That is out answer.

Question 2(Multiple Choice Worth 1 points)
Tomtit [17]

The sequence is " Algebraic, common difference = −10 " ⇒ 1st answer

Step-by-step explanation:

Let us revise the algebraic and geometric sequences

  • The Algebraic sequence is the sequence that has a common difference between each two consecutive terms, like 2 , 5 , 8 , 11 , 14 , .......... the difference between the 5 and 2 is equal to the difference between 8 and 5, and the difference between 11 and 8 and the difference between 14 and 11
  • The geometric sequences is the sequence that has a common ratio between each two consecutive terms, like 3 , -9 , 27 , -81 , ...... the ratio between -9 and 3 as the ratio between 27 and -9 as the ratio between -81 and 27

→  x   :    1    :    2    :    3    :    4

→ f(x) :    5   :   -5    :    -15  :    -25

x represents the positions of the terms

f(x) represents the value of each term

∵ 1st = 5 and 2nd = -5

∵ -5 - 5 = -10

∵ 2nd = -5 and 3rd = -15

∵ -15 - (-5) = -15 + 5 = -10

∵ 3rd = -15 and 4th = -25

∵ -25 - (-15) = -25 + 15 = -10

∴ There is a common difference -10 between each two

   consecutive terms

∴ The sequence is algebraic with common difference -10

The sequence is " Algebraic, common difference = −10 "
