Question

A builder claims that bidets are installed in more than 50% of all homes being constructed today in suburban Lapu-lapu. Would you agree with this claim if a random survey of new homes in this city showed that 54 out of 150 had bidets installed? Use a 0.05 level of significance. Find the critical value, standard test statistic and statistical decision. 

a. this problem is a test on what population parameter? (pick one)
      Mean / Variance / Population Parameter


b. What is the null and alternative hypothesis? (pick one)
      1. Bidets are installed in 50% of all homes being constructed today in suburban Lapu-lapu (p = 0.50); Bidets are installed in LESS THAN 50% of all homes being constructed today in suburban Lapu-lapu. (p < 0.50)
      2. Bidets are installed in 50% of all homes being constructed today in suburban Lapu-lapu (p = 0.50); Bidets are installed in MORE THAN 50% of all homes being constructed today in suburban Lapu-lapu. (p > 0.50)
      3. Bidets are installed in 50% of all homes being constructed today in suburban Lapu-lapu (p = 0.50); Bidets installed in all homes being constructed today in suburban Lapu-lapu is NOT EQUAL TO 50% (p ≠ 0.50)

c. Is it right-tailed, left-tailed or two-tailed?
