tim and his brother are building towers out of blocks. Tim is using blue blocks that are 6 cm tall and his brother is using gree
Karolina [17]

The shortest possible height of tower is 24 cm.

Tim used 4 blue blocks and his brother used 3 green blocks.

Step-by-step explanation:

Given,

Height of blue block = 6 cm

Height of green block = 8 cm

We will take least common multiple to find the shortest possible height.

6 = 2*3

8 = 2*2*2

LCM = 2*2*2*3 = 24 cm

The shortest possible height of tower is 24 cm.

Number of blue blocks used = \frac{24}{6} = 4

Number of green blocks used = \frac{24}{8} = 3

Tim used 4 blue blocks and his brother used 3 green blocks.

48% of their readers own a particular make of car. A marketing executive wants to test the claim that the percentage is actually
oksian1 [2.3K]

Answer:

There is no sufficient evidence to support the executive claim

Step-by-step explanation:

From the question we are told that

     The  population proportion is  p =  0.48

      The  sample proportion is  \r p  =  0.45

       The sample  size is  n  =  300

       The  level of significance is \alpha  =  0.02

The null hypothesis is  H_o  :  p=  0.48

The  alternative hypothesis is  H_a  :  p \ne  0.48

   Generally the test statistics is mathematically evaluated as

           t =  \frac{\r p  -  p  }{ \sqrt{ \frac{p(1 -  p )}{n} } }

=>        t =  \frac{0.45   -  0.48   }{ \sqrt{ \frac{0.48 (1 -  0.48 )}{300} } }

=>       t =  -1.04

The  p-value is mathematically represented as

     p-value  =  2P(z  >  |-1.04|)

Form the z-table  

                 P(z  >  |-1.04|)  =   0.15

=>   p-value  =  2 * 0.15

=>   p-value  = 0.3

Given that  p-value  >  \alpha  we fail to reject the null hypothesis

   Hence we can conclude that there is no sufficient evidence to support the executive claim
