From the previous question. Researchers at the Pennsylvania State University conducted experiments with poplar trees in which one group of trees was given fertilizer and irrigation while the other group was given no treatment. The weights in kilograms of trees in the two groups are shown in the following table. No treatment: 0.14, 0.02, 0.15, 0.37, 0.23 Treatment: 2.20, 0.27, 0.94, 1.07, 2.37 The standard deviation for no treatment is . The standard deviation for treatment is . Round to 3 decimal places.

A study conducted by Pennsylvania State University researchers investigated whether time perception, an indication of a person’s ability to concentrate, is impaired during nicotine withdrawal. After a 24-hour smoking abstinence, a random sample of thirty smokers was asked to estimate how much time (in seconds) had elapsed during an actual 45-second time period test. Summary statistics are shown in the table below. Sample Mean = 50.35 seconds | Sample Standard Deviation = 19.84 seconds a) Find a 90% confidence for...

A study conducted by researchers at Pennsylvania State University investigated whether time perception, an indication of a person's ability to concentrate, is impaired during nicotine withdrawal. After a 24-hour smoking abstinence, 25 smokers were asked to estimate how much time had passed during a 50-second period. The average amount of perceived time that elapsed was 55.827 seconds with a standard deviation of 10.082 seconds. Is there evidence at the 0.10 level that nicotine withdrawal has a negative impact on time...
