- 20 Items were randomly selected from a large inventory Hint: StatisticsOne can find out a sample proportion’s probabilities through the utilization of normal estimation (s) only if specific conditions are fulfilled. It is quite crucial that one pays attention t..
- 200 children aged under 5 years were sampled from a village in Malawi Hint: Statistics"(a) The prevalence of malaria in children under 5 years old in the village is estimated to be 25.5% (51/200). To calculate the 95% confidence interval, we can use the formula:prevalence ± (..
- 5 dice or an online dice rolling simulator which can be found Hint: Statistics The central limit theorem is a concept in probability theory. Accordingly, given a large sample size to represent a population whose variance level is finite, the mean of all samples w..
- 6 students were asked how many times they rebooted their computers Hint: Statistics"Probability mass functions :A probability mass function is a function which gives the probability that a discrete random variable is basically equal exactly to some of the value. Most of th..
- A $90,000 182-day Canadian T-Bill if its quoted yield is 10.48% Hint: I found the answer DeltaP=was -81.06023. Using dp/di=-90000/(1+0.1048*182/365)^2*(182/365), then Delta P=dp/di * Delta i=dp/di * 0.002=-81.06...
- A (hypothetically) invests the principal amount K at time 0 and lets it grow Hint: StatisticsInterest rate swap is a forward contract in which one stream of the future interest payments is exchanged for another which is based on a specified principal amount. It also involves the exc..
- A 10-year study conducted by the American Heart Association provided Hint: StatisticsRegression analysis is the form of a technique of the predictive modelling that investigates the relationship between a dependent or the target, and independent variable i.e., predictor. Reg..
- A 16-run experiment was performed in a semiconductor manufacturing plant Hint: StatisticsThe normal probability plot refers to a graphical method used to assess if a data set is nearly distributed normally or not. Data are usually plotted against theoretical normal distribution ..
- A 1980 study was conducted whose purpose was to compare the indoor Hint: Statistics"1. The null hypothesis is not rejected. As, there is no enough evidence to support the claim that the CO level is lower in non-smoking working areas in comparison to smoking work area..
- A 2012 survey of WSU undergraduate students found that 43% used Pinterest Hint: Statistics"Inferential statistics is a phase that attempts to ‘deduce’, ‘infer, or arrive at ‘conclusions’ regarding a population by using a population sample’s information. A sample size is basically..
- A 2017 Toyota Corolla costs an average of Hint: Statisticsa. 0.0158b. It is assumed that the popualtion from which sample is drawn is normlly distributed...
- A 24 experiment was conducted in a CR design to study the effect load on drill Hint: StatisticsAn ANOVA test is a method used to find out if the results of a survey or an experiment are significant. It helps a researcher to decide whether to reject the null hypothesis or to accept the..
- A 305 mm thick airport rigid pavement is to be constructed as a jointed reinforced Hint: Statisticsa.) A cross-sectional area refers to the area of a shape which has two dimensions the area=L*W ;which is obtained when an object which has three dimensions area=L*W*H, such as a cylinder is ..
- A bag contains 6 coins, 2 of which have a head on both sides while the other 4 coins Hint: StatisticsA probability mass function refers to a function describing the probability that is associated with a random variable. A probability mass function is valid when the discrete random variable ..
