Please solve subparts A,B and no reject. Because its no essay thank u Question This study aims to determine the need for SPKLU (public electric vehicle charging stations) or charging stations (CS) for owners of battery-based electric motorized vehicles (KBLBB) in Indonesia. Data for the year until the end of 2021 recorded as many as 800 KBLBB from various brands (Hyundai 700, BYD 24, Tesla 56, Nissan 20). There is a list of names of KBLBB owners according to the brand. It is suspected that the need for SPKLU differs according to the brand of the car. A. If the sample will be selected as many as 80 KBLBB owners. Determine the sampling technique that is in accordance with the population information above. And write down the steps / stages until 80 people are selected (choose 80 people out of 800 people) B. Explain the difference between random and non-random sampling techniques. And explain the sampling technique in each of these sampling techniques (randon and non-random)

CHART ATTACHED. PLEASE USE EXCEL FORMULAS FOR ME TO FOLLOW WHEN APPLICABLE The Standard Issue Test Prep company offers an ACT prep course designed to help students improve their scores on the ACT exam. A mock exam is given at the beginning of the course to see where students are starting from. A sample of 27 students' scores are taken and given below: Using this data, answer questions below. CAUTION! If you are using your calculator for Parts A and B, double-check that you entered the data in your calculator correctly. One minor mistake in data entry can lead to a drastically different answer! Find the mean: ___________________. Round your answer appropriately. Find the standard deviation: ___________________. Round your answer appropriately. Assuming the population is normally distributed, construct a 95% confidence interval for the mean mock exam. Show all relevant work and follow these expectations: Your work should be easy to read and follow. Use…
Provide an appropriate response using correct mathematical notation and vocabulary in the space below. Use the equation editor as needed for mathematical notation.On a recent Statistics test, the scores were 15, 66, 66, 81, 82, 83, 85, 88, 90, 92, 93, and 95. Is the mean a good representation of the center of data? If not, explain why not and identify a better representation of the center of data.
Daily High Temp. The histograms describe the high temperatures in a certain city on each day of one month. The histogram on the left uses class widths of 3°F and the histogram on the right uses class widths of 6°F. Assume that temperature is measured and recorded as whole number values so that the first class would be 64°F-66°F when using a class width of 3°F. Complete parts (a) through (c) below. Daily High Temp. 64 70 76 82 88 94 Degrees Farenheit 64 70 76 82 88 94 Degrees Fareniheit a. During this month, there tends to be two types of weather. The city experiences either cool, foggy days or hot, sunny days. Which of the two histograms better reflects this? O A. The histogram with class widths of 6°F, because the histogram has larger class widths. O B. The histogram with class widths of 6°F, because there are no gaps in the histogram. OC. The histogram with class widths of 3°F, because the two distinct groups of data are separated by a gap in the histogram. O D. The histogram with…
