Hello,I have been working on the following question:An Air Quality

Question Hello,I have been working on the following question:An Air Quality instrument logs when standards are not met and 1 whenstandards are met. The log is saved to file DATA First,compute the proportion meeting standard as the mean of  Air Quality values. Second, at alpha = 0.10 (sensitive, exploratory), test the hypothesis that proportion of times that air quality meets standards is at least 90% From the data below I came up with : The pvalue of 0.006 indicates that the data provide overwhelming evidence against HO: π≥ 0.90. HO is rejected at α = 0.10. Send out an air quality alert. (Is this correct?) Please refer to data below, and let me know if you require more information.Thanks  Time 0:00:00 0:00:30 0:01:00 0:01:30 0:02:00 0:02:30 0:03:00 0:03:30 0:04:00 0:04:30 0:05:00 0:05:30 0:06:00 0:06:30 0:07:00 0:07:30 0:08:00 0:08:30 0:09:00 0:09:30 0:10:00 0:10:30 0:11:00 0:11:30 0:12:00 0:12:30 0:13:00 0:13:30 0:14:00 0:14:30 0:15:00 0:15:30 0:16:00 0:16:30 0:17:00 0:17:30 0:18:00 0:18:30 0:19:00 0:19:30 0:20:00 0:20:30 0:21:00 0:21:30 0:22:00 0:22:30 0:23:00 0:23:30 Air Quality 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1

Hello,I am working on a problem:With 80% confidence, for sample

Question Hello,I am working on a problem:With 80% confidence, for sample proportion 0.52 and sample size 28 what is the upper confidence limit with 2 decimal placesUpper limit = p z*pq/n​ at 80% z=1.28Hence upper limit = 0.52 1.28*sqrt(0.56*0.44/28)= Is this correct?

Q) Big Deal Real Estate surveyed prices per square foot

Question Q) Big Deal Real Estate surveyed prices per square foot in the valley and foothills of Hoke-a-mo, Utah. Based on BD’s are prices per square foot equal at α= 0.01   a)   The critical value is 2.977 since this is a two tail scenario. The test statistic is 1.513. Since the test statistic > the critical value, the test statistic does lie in the area of rejection. Reject the null hypothesis. The prices per square foot are not equal at alpha= .01b)    The critical value is 2.977 since this is a two tail scenario. The test statistic is 2.239. Since the test statistic < the critical value, the test statistic does not lie in the area of rejection. Do not reject the null hypothesis. The prices per square foot are equal at alpha= .01 ( I came up with this answer-is this corrrect?)  c) The critical value is 2.977 since this is a two tail scenario. The test statistic is 1.936. Since the test statistic < the critical value, the test statistic does not lie in the area of rejection. Do not reject the null hypothesis. The prices per square foot are equal at alpha= .01           d) The critical value is 2.977 since this is a two tail scenario. The test statistic is 1.513. Since the test statistic < the critical value, the test statistic does not lie in the area of rejection. Do not reject the null hypothesis.
