1. Getting a good night's sleep is essential for teenage students to perform optimally during school.According to the National Sleep Foundation, high school students need at least 8 hours of sleep foroptimal performance at school the following day. Based on a sleep study of 459 students, a 95%Confidence Interval for the true mean sleeping time (in hours) was calculated to be (7, 7.28) hours.a. Based on the Confidence Interval given, can you say with high degree of confidence that thetrue mean of sleeping time is below 8 hours? In a sentence or two explain why or why not.b. If we were to increase our sample size, what would we expect to happen to the confidenceinterval? Get wider/ get narrower/ stay the same?c. If we were to increase our level of confidence, what would we expect to happen to the confidenceinterval? Get wider/ get narrower/ stay the same?

The sample size, i.e., the sampled no. o students, n=459. The 95% CI for the true mean sleeping time…

In order to determine if weather conditions play a significant role in how a disease effects wheat, fields of wheat are exposed to this disease over three consecutive summers, 2002-2004. The fields are later rated on a scale of 0.0 (resistant) to 10.0 (susceptible) based on how the disease has infected the field. The results are shown below along with the ANOVA table. At the 95% confidence level, compare the mean scores across the three years. 2002 2003 2004 7 7.3 5 4.7 8 3 8 5 2 3.3 3.3 7 6.3 4.7 7.3 7 3.7 8 7 4.3 6. 7 4.3 2 6.3 6.7 ANOVA Source of Variation df MS Treatment 20.97333 2 10.48667 4.127165 Error 76.22667 30 2.540889 Total 97.2 32
