A journal reported that the average screen time of teenagers is 6.77 hours per week. You gathered 30 independent samples from your class and obtained an average screen time of 7.8 hours per week, with a sample standard deviation of 2.9 hours. At alpha = 0.10, is this enough evidence to say that the average screen time of your class is higher than the reported screen time? Compute the critical value

A state fish hatchery raises trout for stocking streams and lakes. The size of the fish at release time canbe controlled to a fair degree by varying the rate of feeding. The target is a mean of 14 ounces; if the fishare too small, those who catch the fish aren’t happy. A random sample of 82 fish were weighed at time ofrelease and it was determined that the mean was 13.78 ounces with a standard deviation of 1.84 ounces.Test to determine if the fish being released have a population mean less than 14 ounces at the 0.05significance level.
Neelesh Pant is the production manager for Citrus Groves Inc., located just north of Ranikhet, Uttarakhand. Neelesh is concerned that the last 3 years' late freezes have damaged the 2,500 orange trees that Citrus Groves owns. In order to determine the extent of damage to the trees, Neelesh has sampled the number of oranges produced per tree for 42 trees and found that the average production was 525 oranges per tree and the standard deviation was 30 oranges per tree. (a) Estimate the population standard deviation from the sample standard deviation. (b) Estimate the standard error of the mean for this finite population. (c) Construct a 98 percent confidence interval for the mean per-tree output of all 2,500 trees. (d) If the mean orange output per tree was 600 oranges 5 years ago, what can Neelesh say about the possible existence of damage now?
An article reports an investigation into the toxicity of bilirubin on several cell lines. Ten sets of human liver cells and 5 sets of mouse fibroblast cells were placed into solutions of bilirubin in albumin with a 1.4 bilirubin/albumin molar ratio for 24 hours. In the 10 sets of human liver cells, the average percentage of cells surviving was 53.9 with a standard deviation of 10.7. In the 5 sets of mouse fibroblast cells, the average percentage of cells surviving was 73.1 with a standard deviation of 9.1. Let μXμX represent the population mean for the mouse cells and let μYμY represent the population mean for the human cells. Find a 98% confidence interval for the difference μX−μYμX−μY . Round down the degrees of freedom to the nearest integer and round the answers to three decimal places. The 98% confidence interval is ( , ).
The physical plant at the main campus of a large state university recieves daily requests to replace florecent lightbulbs. The distribution of the number of daily requests is bell-shaped and has a mean of 48 and a standard deviation of 7. Using the empirical rule (as presented in the book), what is the approximate percentage of lightbulb replacement requests numbering between 27 and 48?
An electronic company manufactures electrical resistors with Rave = 40 Q and SD= 2, same unit. What is the probability that the manufactured products will exceed 43 Q? Assume normal distribution. O 17.24% O 82.76% O 93.32% O 6.68%
A sample of 62 city blocks were taken in Black majority neighborhoods and 58 city blocks in non-Black majority neighborhoods. We are interested in looking at the concentration of Nitrogen Dioxide (NO2), an air pollutant. The average amount of NO2 in Black majority blocks is 11.0362 with a standard deviation of 4.3976, and the average amount of NO2 in non-Black majority blocks is 10.4195 with a standard deviation of 4.9371. Test the claim that the mean NO2 concentration is greater in Black majority than non-Black majority blocks at a = 0.10. Assume that the data come from normal populations with equal variances.

In an automobile repair and service industry, the average number of defective items in all the lots of automobile parts produced by a machine last week was 8. The supervisor believes that the mean number of defective parts produced by the same machine will differ in the present week. To test whether the average differs from 8, he samples 30 lots to obtain the mean number of defective parts to be 9 with a standard deviation of 3.Using the critical value approach, identify the decision at the 5% level of significance. Group of answer choices The decision is not to reject H0 because the test statistic does not fall in the rejection region (-∞,-1.960] U [1.960, ∞).

In a sample of 87 people who have had strokes, the average cholesterol level was 258 with a standard deviation of 41.6. In order to test the hypothesis (at the 10% level of significance) that the average cholesterol level of people who have had strokes was at least 240, what is the critical value?
The current machine for completing a specific operation in a manufacturing facility has a known average cycle time of 12.45 minutes. An engineer has identified a potential replacement machine from which 150 samples are taken. These 150 samples have an average cycle time of 10.32 minutes with a standard deviation of 5.14 minutes. The engineer must provide statistical evidence of whether the machine works at a five percent level of significance to management. What analysis would you complete to answer this question?
