The percentage of high school students who graduate is equal to 55%.
Gnom [1K]

Answer:

Type 1 error:

D)Reject the null hypothesis that the percentage of high school students who graduate is equal to 55 % when that percentage is actually equal to 55 %.

Type 2 error:

B,)Fail to reject the null hypothesis that the percentage of high school students who graduate is equal to 55 % when that percentage is actually less than 55 %.

Step-by-step explanation:

When something that is true, is been rejected, then it's reffered to as Type I, on the other hand when

Whensomething that is false is been failed to be rejected then it's reffered to as that is Type II

Type I ;

This is to reject Hypothesis when Hypothesis is true, i.e rejecting of the null when it's true.

For instance from the question,

The percentage of high school students who graduate is equal to 55%. Then to get the Type1 , One would say the percentage of high students who graduated is not 55% when it is in actual sense

Type II ;

This is happen when we accept a false null hypothesis which means it takes place when We fail to reject Hypothesis when it is False.

For instance, from the question which says The percentage of high school students who graduate is equal to 55%. Then for type II to occur One would say it is 55% when it is really not 55%.

It's easy it's called Two-way tables please help
Vesnalui [34]

Answer: The filled out table is shown below in the attached image

===========================================================

Explanation:

The letters A through J are one way to fill out the table. Though there are other possible orders.

Start at letter A, which is from the fact we have 40 people total

Then move to letter B. This is the total number who like pasta (26)

We have C = A-B = 40-26 = 14 people who don't like pasta

--------------

Now move to cell D. This is the total who don't like netball, which is 21 people. There are E = A-D = 40-21 = 19 people who do like netball.

F = 4 is the number of people who don't like either thing (netball or pasta). So G = D-F = 21-4 = 17 people like pasta but don't like netball.

Of those people who like netball (E = 19), we have 9 who also like pasta. This is in cell H in the upper left corner. This means J = E-H = 19-9 = 10 people like netball but don't like pasta.

----------------

So we have these values

  • A = 40
  • B = 26
  • C = 14
  • D = 21
  • E = 19
  • F = 4
  • G = 17
  • H = 9
  • J = 10

Can someone please help me
natita [175]
Tricky one because they're asking for C not x.  

2x + 2x + 6x = 180

10x = 180

x = 18

C = 2x = 36

Last one
