Dlivia works at a company that creates mobile phones. She wanted to estimate the mean amount of tim new phone's battery lasts with regular use after a full charge. She took a random sample of 6 of these pa and randomly assigned each of them to a volunteer. She instructed them to fully charge the phones and them as they regularly would until the battery died (without recharging the phone). Here are the data the reported: Phone 1 3 4. 5 Battery life (hours) 8.0 6.0 10.5 9.0 8.5 12 Mean * = 9 hours Standard deviation 2.07 hours Assume that all conditions for inference are met.

The table below shows the frequency of AP Biology scores for a high school class. AP Score Frequency 1 5 2 7 3 6 4 4 5 3 Find the mean and median. Mean = 1.67 and Median = 2 Mean = 2.72 and Median = 3 Mean = 2.72 and Median = 7 Mean = 4.53 and Median = 4 Mean = 4.53 and Median = 3
A music fan claims that R&B songs and Rap songs differ in terms of their positivity. The individual collected two independent random samples from the population of all songs on Spotify. Fifteen R&B songs and another fifteen Rap songs were collected and their Valence was recorded. Remember, the variable Valence is measured on a 0 to 1 scale. Songs with high valence sound more positive (e.g. happy, cheerful, euphoric), while songs with low valence sound more negative (e.g. sad, depressed, angry). We will subtract (R&B – Rap) and use the 10% significance level. Assume the Central Limit Theorem conditions hold. The data set is called RBRapSample31. Please import the data set into Rguroo or find it in our group. Define the population parameter in context and symbols in one sentence. State the hypotheses you would use to test the claim that a difference exists in the mean Valence between R&B and Rap songs using correct notation.

An outbreak of the deadly Ebola virus in 2002 and 2003 killed 91 of the 95 gorillas in 7 home ranges in the Congo. To study the spread of the virus, measure " distance" by the number of home ranges separating a group of gorillas from the first group infected. Here are data on distance and number of days until deaths began in each later group: Distance xx 2 5 4 4 4 6 Days yy 4 21 29 40 47 49 Use a calculator or software to find the following values.

The chlorine added to swimming pools to combat relatively short shelf before it loses its effectiveness. Records indicate that the mean shelf life of a 5 gallon jug of chlorine is 2,160 hours (90 days). As an experiment, Holdlonger was added to the chlorine to whether it would increase the shelf life of the chlorine. A sample of nine jugs of chlorine had these shelve lives (in hours): 2,159, 2, 170, 2,180, 2,179, 2,160, 2,167, 2,171, 2,181 and 2,185. At the .025 significance level, has Holdlonger increased the shelf life of the chlorine? S=9.3823, sample mean=2172.44 STATE THE NULL AND ALTERNATE HYPOTHESIS. Determine the critical value for the decision rule.
