Perform a Hypothesis Test using the P-value. a) Identify the claim and state the null hypothesis and alternative hypothesis, b) use the calculator to find the P-value, c) decide whether to reject or fail to reject the null hypothesis, and d) interpret the decision in the context of the original claim.  A telephone company claims that 20% of its customers have at least two telephone lines.  The company selects a random sample of 500 customers and find that 88 have two or more telephone lines. At a=0.05, does the data support the claim.  Your answer should follow this order: a.) State the null and alternative hypotheses b.) P-value = ? c.) Do you Reject Ho or Fail to Reject Ho? d)  In a complete sentence state the conclusion.
