I need help with these questions please:

According to the World Health Organization (WHO), Body Mass Index (BMI) is a statistic that indicates the ratio of a person's weight to their body volume. The Center for Disease Control (CDC) uses the table to classify children from ages 2 to 20. Because BMI values change as children grow, the CDC uses percentiles rather than xed values for BMI. Percentiles provide a basis of comparison for BMI over time. Weight status Percentile range Underweight Less than the 5th percentile Healthy weight 5th percentile to less than the 85th percentile Overweight 85th to less than the 95th percentile Obese Equal to or greater than the 95th percentile Based on data from WHO, a representative sample of 13yearold males could consist of the following 15 values. 16.8,17.1,14.8,16.3, 20.1,15.7,19.1,17.8,19.6,20.8,17.5,18.7,18.2, 28.2, 22.3 The Centers for Disease Control and Prevention (CDC) estimated the percent of individuals in each state who are classied as overweight or obese in different years. They calculated the estimates separately for three different age classes, including children (24 years old), adolescents (students in grades 912), and adults (aged 18 years and older). The boxplots display the given ve-number summaries (Min, First Quartile (Q 1) , Median, Third Quartile (Q3) , Max) computed based on the data for two different age classes. Match the appropriate descriptions to the data sets. Answer Bank the distribution is skewed to the right 25% of the values are less than 21.30 [ the distribution is skewed to the left | 25% of the values are more than 20.60 25% of the values ale more than 15.82 25% of the values are less than 8.70 25% of the values are more than 31.08 the distribution is close to symmetrical 25% of the values are more than 35.10 25% of values are less than 26.40 25% of values are less than 13.42 W 20 22 24 26 28 30 32 34 36 Adults who were obese in 2013 (%) Min Q1 Median Q3 Max 21.30 26.40 29.40 31.08 35.10 % flllIlfI 8 10 12 14 16 18 20 22 Children who were obese in 2012 (%) Min Q1 Median Q3 Max 8.70 13.42 14.65 15.822060 Suppose Chloe works for a non-prot organization that raises funds to provide counseling for primary caregivers in singleparent families. Chloe's boss wants to know more about the likely ages of parents who will receive counsel from their organization. Chloe's boss asks Chloe to provide an interval of the middle 93.75% of ages of single parents. Chloe knows that the mean age of the primary caregivers in single-parent families in her community is 45 years old and that the corresponding standard deivation is 7, however she does not know how these ages are distributed. Using Chebyshev's inequality, what interval should Chloe give for the middle 93.75% of ages of single parents in her community? Round your answers to the nearest whole number. Avoid rounding within calculations. interval lower bound = C] interval upper bound = C] Last summer, the Smith family drove through seven different states and visited various popular landmarks. The prices of gasoline in dollars per gallon varied from state to state and are listed below. $2.17, $2.97, $2.70, $3.80, $3.09, $2.75, $3.53 Click to download the data in your preferred format.

Suppose that Kevin is playing a video game in which additional enemies spawn randomly during a boss fight. He read in an online guide that the wait time until a new enemy spawns is uniformly distributed between 35 s and 45 s. 30 35 40 45 50 If an enemy has just spawned, what is the median amount of time until the next enemy spawns? What is the mean amount of time until the next enemy spawns? SA scale is tested by repeatedly weighing a standard 9.0 kg weight.
