The average cost of a hotel room in New York is said to be $150 per night. To determine if this is true, a random sample of 30 hotels is taken and the results are shown below table Test the appropriate hypotheses at a = 0.05 Hotel Price daily 160 170 Mean 174.8 200 standard deviation 55.77 70 300 120 130 180 120 158 189 145 155 168 145 190 200 205 220 250 300 170 170 180 290 120 110 100 150 179 Do not reject the null (Ho: ? = 150) because the confidence interval is (154.8433, 194.7567) Do not reject the null (Ho: ? = 150) because the confidence interval is (153.9751, 195.6249) Reject the null (Ho: ? = 150) because the confidence interval is (154.8433, 194.7567) Reject the null (Ho: ? = 150) because the confidence interval is (153.9751, 195.6249)

Step 1
We want to test if the average cost of a hotel room in New York is $150 per night. So, our null hypothesis (H0) is that the average cost is $150, and the alternative hypothesis (H1) is that the average cost is not $150. H0: μ = 150 H1: μ ≠ 150 Show more…

The average cost of a hotel room in New York is said to be $168 per night. A random sample of 25 hotels resulted in x = $172.50 and s = $15.40. Test at the α = 0.05 level. (Assume the population distribution is normal)
