Answer:

Null Hypothesis: p = 0.65.

Step-by-step explanation:

The null hypothesis is the expected population population, from an assumption deriving for example, from a previous experiment.

According to a researcher who was quoted in a New York Times article in March, 2011, 65% of U.S. community college students must take at least one remedial course in English

This means that the expected value of the population proportion is p = 0.65, which is the null hypothesis.

A closet containing 120 pieces of clothing is made
lapo4ka [179]

Answer:

5/9

Step-by-step explanation:

Let's define:

  • sw: number of sweaters
  • j: number of jeans  
  • sk: number of skirts

The following three equations are established from the question:

sw + j + sk = 120

sw/j = 8/3

j/sk = 3/4 or sk/j = 4/3

Dividing the first equation by j, we get:

sw/j + j/j + sk/j = 120/j

8/3 + 1 + 4/3 = 120/j

5 = 120/j

j = 120/5 = 24

sw = 24*8/3 = 64

sk = 24*4/3 = 32

After the replacement the new number of jeans and skirts are:

j' = 24 - 4 = 20

sk' =  32 + 4 = 36

the new ratio of jeans to skirts is:

j'/sk' = 20/36 = 5/9
