Answer:

23. $8

18. x=4p

Step-by-step explanation:

23.

$32 equals 1-1/5=4/5ths of her money (x)

32=(4/5)x

x=40

Now we know Anna has $40 dollars. If she spent 1/5th of it on the book,

40*(1/5)=8

Anna spent $8 on the book

An airline promotion to business travelers is based on the assumption that two-thirds of business travelers use a laptop compute
skad [1K]

Answer:

a

  The null hypothesis is  H_o  :  p =  0.67

   The alternative hypothesis is  H_a : p \ne 0.67

b

 The sample proportion is \^ p  =  0.65

Step-by-step explanation:

From the question we are told that

     The sample size is  n =  546  

      The number of people that use a laptop overnight is  k = 355

    The population proportion is  p =  \frac{2}{3}  =  0.67

   Generally

  The null hypothesis is  H_o  :  p =  0.67

   The alternative hypothesis is  H_a : p \ne 0.67

Gnerally the sample proportion is mathematically represented as

        \^ p  =  \frac{ k}{n}

=>     \^ p  =  \frac{ 355}{546}

=>     \^ p  =  0.65
