# A bag contains ﬁfteen balls distinguishable only by their colours; ten are blue and ﬁve are red. I reach into the bag with both hands and pull out two balls (one with each hand) and record their colours. What is the random phenomenon?, and What is the sample space?

| No Comments Random phenomenon is the process of selecting two balls from a bag of different colored balls with unknown composition. It is an example of a discrete random variable, which can be described as a set of outcomes that can each occur with some probability.Get the Complete Custom Written Paper Written by Real Humans Who have exceptionally Excelled in their Studies and understand […]

# Describe the sample space and all 16 events for a trial in which two coins are thrown and each shows either a head or a tail.

| No Comments The sample space is an important concept in probability and inferential statistics, as it provides a framework for examining the outcome of events. It is defined as the set of all possible outcomes for any given experiment or trial. In this case, we are looking at the outcomes of two coins being thrown and each showing either a head or a tail.

# The average number of yearly accident at a traffic intersection is 5. Find the probability that there are exactly three accidents at the same intersection this year.

| No Comments The probability of exactly three accidents at a traffic intersection in any given year is calculated using the Poisson distribution, which describes the probability of a certain number of occurrences over a certain amount of time. The formula for this calculation is P(x) = (e^-μ)(μ^x)/ x!, where x is the desired number of occurrences (in this case, 3), e is Euler’s constant […]

# Compute a one-sample t-test to find out whether the stress scores reported by your sample are significantly different from those of the population of online students.

| No Comments A one-sample t-test is a statistical tool used to compare the mean of a sample to the mean of an entire population. It evaluates whether the differences between the two means are statistically significant. In this example, we will use a one-sample t-test to determine if the stress scores reported by our sample of online students are significantly different from those of […]

# How do you think the field of psychology should balance the issue of type I vs. type II errors?

| No Comments Type I and Type II errors are two of the most important concepts in psychology, and many psychologists grapple with how to optimize their research for them. Type I error refers to a false positive—when results suggest a phenomenon is occurring when it actually isn’t. For example, if a researcher incorrectly concludes that an observed difference between two groups was statistically significant […]

# Explain what a confidence interval is and how it helps you to better understand the parameter of the population you are interested in …

| No Comments A confidence interval is a range of values associated with an estimate of a population parameter, such as the mean or proportion. It is used to provide information about how reliable and precise the estimate is. Confidence intervals quantify the level of uncertainty associated with an estimated value. The wider the confidence interval, the greater the uncertainty about where the true population […]

# Does the cream have any effect?

| No Comments Creams are topical products that contain ingredients in them which claim to be beneficial for skin, hair or nails. Although there is no scientific evidence to support the fact that creams can actually give meaningful improvements in skin conditions or even prevent ageing, many users have reported positive results after using them. Creams are widely available and come in various forms such […]
