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.

What is the null and alternative hypothesis? *
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)
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)
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)
