Kelsi is curious to see if ST 243Z campus students typically got their first cell phone at a younger age than they (Kelsi) got their first phone. To investigate this, they take a random sample of 20 students from all ST 243Z campus students this Winter 2024 term and find those students had an average age of 11.85 years when they reported receiving their first phone. The standard deviation of the population, ox, is known to be 1.91 years. The histogram and boxplot of the sample are provided below. We are interested at exploring at the 90% confidence level. What is the average age for getting their first phone of all ST 243Z campus students in Winter 2024? 8 9 Age when got first phone 10 11 12 Age (years) 13 14 15 8 9 Age when got first phone T 10 11 12 Age (years) T 13 T 14 T 15 1. In 1-3 sentences, describe the distribution of the sample, including shape, center, spread, context, and outliers (if relevant).
