Question

An airline promotion to business travelers is based on the assumption that two-thirds of business travelers use a laptop computer on overnight business trips. a. State the hypotheses that can be used to test the assumption. H 0: p Select H a: p Select b. What is the sample proportion from an American Express sponsored survey that found 355 of 546 business travelers use a laptop computer on overnight business trips

Answer 1

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

        $\^ p = \frac{ k}{n}$

=>     $\^ p = \frac{ 355}{546}$

=>     $\^ p = 0.65$
