A shopping centre wants to examine the amount of space required for parking. Studies indicated that 61% of staff and shoppers use public transportation. A survey of 1,002 was taken, and 580 responded that they used public transportation. a. State the null hypothesis and the alternate hypothesis. Round the final answers to 2 decimal places. H0: p = H1: p ≠ b. State the decision rule for 0.05 significance level. (Negative answer should be indicated by a minus sign. Round the final answers to 2 decimal places.) Reject H0 if z > or z < . c. Compute the value of the test statistic. (Negative answer should be indicated by a minus sign. Round the final answer to 2 decimal places.) Value of the test statistic d. At the 0.05 significance level, is it reasonable to conclude that the survey results indicate a change? H0. There is evidence to indicate that the results have changed.
As P-value is less than -value, null hypothesis will be rejected. So the survey result indicates change from study result.

The following hypotheses are given. H0 : π ≤ 0.83 H1 : π > 0.83 A sample of 100 observations revealed that p = 0.87. At the 0.10 significance level, can the null hypothesis be rejected? State the decision rule. (Round your answer to 2 decimal places.) Compute the value of the test statistic. (Round your answer to 2 decimal places.) What is your decision regarding the null hypothesis? Do not reject H0. Reject H0. question 2: The number of...
The following hypotheses are given. HO: IT = 0.40 HAT+0.40 A sample of 120 observations revealed that p=0.30. At the 0.05 significance level, can the null hypothesis be rejected? a. State the decision rule. (Negative amounts should be indicated by a minus sign. Round your answers to 2 decimal places.) Reject HO and accept H1 when z< or z> b. Compute the value of the test statistic. (Negative amount should be indicated by a minus sign. Round your answer to...
Required information [The following information applies to the questions displayed below.] A recent national survey found that high school students watched an average (mean) of 6.6 DVDs per month with a population standard deviation of 1.00 hour. The distribution of DVDs watched per month follows the normal distribution. A random sample of 30 college students revealed that the mean number of DVDs watched last month was 6.00. At the 0.05 significance level, can we conclude that college students watch fewer...
A study was conducted to determine if there was a difference in the humor content in British and American trade magazine advertisements. In an independent random sample of 283 American trade magazine advertisements, 59 were humorous. An independent random sample of 198 British trade magazines contained 28 humorous ads. (1) State the decision rule for .10 significance level: H0: πA = πB; H1: πA ≠ πB. (Negative values should be indicated by a minus sign. Round your answers to 2...
A recent national survey found that high school students watched an average (mean) of 7.6 movies per month with a population standard deviation of 0.5. The distribution of number of movies watched per month follows the normal distribution. A random sample of 41 college students revealed that the mean number of movies watched last month was 7.0. At the 0.05 significance level, can we conclude that college students watch fewer movies a month than high school students? State the null...
A recent national survey found that high school students watched an average (mean) of 7.1 movies per month with a population standard deviation of 1.0. The distribution of number of movies watched per month follows the normal distribution. A random sample of 41 college students revealed that the mean number of movies watched last month was 6.6. At the 0.05 significance level, can we conclude that college students watch fewer movies a month than high school students? State the null...
A recent national survey found that high school students watched an average (mean) of 7.8 movies per month with a population standard deviation of 0.5. The distribution of number of movies watched per month follows the normal distribution. A random sample of 30 college students revealed that the mean number of movies watched last month was 7.3. At the 0.05 significance level, can we conclude that college students watch fewer movies a month than high school students? State the null...
The cost of weddings in the United States has skyrocketed in recent years. As a result, many couples are opting to have their weddings in the Caribbean. A Caribbeanvacation resort recently advertised in Bride Magazine that the cost of a Caribbean wedding was less than $10,000. Listed below is a total cost in $000 for a sample of8 Caribbean weddings. At the .005 significance level is it reasonable to conclude the mean wedding cost is less than $10,000 as advertised?9.5,...
In order to conduct a hypothesis test for the population proportion, you sample 400 observations that result in 212 successes. (You may find it useful to reference the appropriate table: z table or t table) H0: p ≥ 0.54; HA: p < 0.54. a-1. Calculate the value of the test statistic. (Negative value should be indicated by a minus sign. Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.) H0: p = 0.54;...
