(Use Exponential Distribution) It is said that the average lifespan of a smartphone produced by a company is 5 years and follows an exponential distribution. Find the probability that this smartphone will last more than 6 years. Round to 4 decimal places. (for example, 0.0233333 should be written as 0.0233. If written as 2.3333%, the answer will be incorrect.)

Which of the following is used to measure the performance of a model on training data

[Use Exam1-Data.xlsx] Find the Z-score of the “PER” value of the observations for all years and companies, and find the skewness of the distribution of the values ​​excluding any outliers with Z-score higher than 3 or lower than -3 using filter. (For example, if 1 out of 10 observations is an outlier, you can discuss the distribution of the 9 observations after filtering out the 1. DO NOT REMOVE THE OBSERVATIONS)You can check the distribution with a clustered column chart. A left-skewed distribution means a distribution with a tail that is longer on the left than on the right. A right-skewed distribution means a distribution with a tail that is longer on the right than on the left. Normal distribution means a distribution that is not skewed in any way. Exam1_Data.xlsx

Use the following Case Study to answer the questions below: Kira, a 3-year-old female, is admitted to the pediatric intensive care unit (PICU) with a diagnosis of bacterial meningitis. Her parents report a 2-day history of fever, irritability, decreased appetite, and vomiting. This morning, they noticed she was less responsive and had a high-pitched cry. Initial Assessment: Vital Signs: Temp 102.8°F (39.3°C), HR 130 bpm, RR 28 breaths/min, BP 110/60 mmHg, SpO2 96% on room air Lethargic, arouses only to painful stimuli. Left pupil 4mm, sluggishly reactive to light; Right pupil 3mm, briskly reactive to light. Anterior fontanelle tense and bulging, withdraws bilateral upper and lower extremities to pain stimuli, no focal deficits noted. Gag reflex present, positive Kernig’s and Brudzinki’s signs. High pitched inconsolable crying. Skin turgor slightly decreased. Past Medical History: Full-term infant, received all age-appropriate vaccinations. No significant past medical history. No recent travel or exposure to sick contacts reported by parents other than a mild cold 1 week prior 1. Based on Kira’s initial assessment findings, which of the following is the most concerning indicator of increased intracranial pressure (ICP) in a 3-year-old? (Place answer for this question in first blank)           A. Heart rate of 130 bpm           B. Temperature of 102.8°F (39.3°C)           C. Sluggishly reactive and unequal pupils           D. Positive Kernig’s and Brudzinski’s signs 2. The nurse is developing a plan of care for Kira. Which nursing intervention is the highest priority for a patient with suspected increased ICP? (Place answer for this question in second blank)        A. Administering antipyretics to reduce fever        B. Maintaining a quiet and dimly lit environment        C. Elevating the head of the bed to 30 degrees with the head in a neutral position        D. Administering broad-spectrum antibiotics as ordered 3. The nurse is monitoring Kira for signs of worsening neurological status. Which of the following, if observed, would indicate a late and critical sign of increased ICP and impending brain herniation? (Place answer for this question in third blank)      A. Restlessness and irritability               B. Headache and nausea      C. Widening cranial sutures and increased head circumference      D. Hypertension, bradycardia, depressed/irregular respirations
