Lucas G. - "The central limit theorem tells us that as we repeat the sampling process of an statistic (n > 30), the sampling distribution of that statistic approximates the normal distribution regardless of the original population's distribution. This theorem is useful because it allows us to apply inference with tools that assume normality like t-test, ANOVA, calculate p-values hypothesis testing or regression analysis, calculate confidence intervals, etc."See full answer

Katherine B. - "We have detailed monitoring and meetings dedicated to discussing the health of the conversion business. When I’ve seen drops in the conversion rate, the first thing I do to diagnose the issue is to work backwards through the conversion funnel. For example, if I see a drop in user adoption rates, I will evaluate if there are any product experiments that could be negatively affecting adoption. Likewise, was there a technical outage that could have caused a drop? Segmentation and cohorting is also"See full answer

Create notification service on the existing app. - that will be a micro service A: Since"See full answer

Alan T. - "The difference between convex and nonconvex functions lies in their mathematical properties and the implications for optimization problems. Convex Functions:A convex function has a shape where any line segment connecting two points on its graph lies entirely above or on the graph. This property ensures that any local minimum is also a global minimum, making optimization straightforward and reliable. Convex functions are critical in machine learning and optimization tasks because of th"See full answer

David I. - "As I understand it, you’d like me to design a mobile native application (for iOS or Android) that helps people manipulate data similar to that of Microsoft Excel or Google Sheets. You can add and import data, edit it, run calculations, regressions, and generate charts and graphs. If it’s ok with you, I’d like to confine the design to iOS, and based on my knowledge of how a product manager uses a spreadsheet. I’d like to approach this problem by first identifying the goal of the app. Since we’r"See full answer
