Show transcribed image text A company that produces cell phones claims its standard phone battery lasts longer on average than other batteries in the market. To support this claim, the company publishes an ad reporting the results of a recent experiment showing that under normal usage, their batteries last at least 34 hours. To investigate this claim, a consumer advocacy group asked the company for the raw data, which are shown to the right. Find a 95% confidence interval and state your conclusion. Explain how you dealt with any outliers Time 32 32 30 32 33 31 31 56 35 31 30 30 Plot the data. Choose the correct histogram below. O c. 60 Battery Life (hours) 60 60 Battery Life (hours) 60 Battery Life (hours) Battery Life (hours) Are any of the observations outliers? Explain 0 A. The histogram shows two extreme outliers. With these values included, the conditions for inference are violated O B. The histogram shows that there is one extreme outlier Since the sample size is large enough, the Nearly Normal Condition is still satisfied ° C. The histogram shows that there are no outliers. The conditions for inference are satisfied 0 D. The histogram shows that there is one extreme outlier. With this value included, the conditions for inference are violated Find a 95% confidence interval for the true mean. What do you conclude about the claim? If there are outliers, find intervals with and without the outliers present
