Problem 7A new formulation of concrete has been designed for a particular building application.Naturally, the strength of concrete produced with the new formulation had to be tested for itsstrength capability. The compressive strength of 12 specimens were tested, as shown below.221622812237226322492318220422552225227523012295a. With a simple histogram, draw conclusions about the normality of these observations.Assume normality regardless.b. Calculate a 95% confidence interval for mean compressive strength.c. Calculate a 95% confidence interval for standard deviation of compressive strength.

Given, the compressive strength of 12 specimens - (2216, 2237, 2249, 2204, 2225, 2301, 2281, 2263,…

Registered nurses earned an average annual salary of $69,110. For that same year, a survey was conducted of 41 California registered nurses to determine if the annual salary is higher than $69,110 for California nurses.

Use the Empirical Rule. The mean speed of a sample of vehicles along a stretch of highway is 68 miles per hour, with a standard deviation of 3 miles per hour. Estimate the percent of vehicles whose speeds are between 65 miles per hour and 71 miles per hour. (Assume the data set has a bell-shaped distribution.) Approximately nothing% of vehicles travel between 65 miles per hour and 71 miles per hour.
QUESTION 12 In the video game Animal Crossing: New Horizons, you can catch and sell both fish and sea creatures. Alison learns that sea creatures sell for a mean of u = 3,345 bells with a standard deviation of o = 3,684 bells ("bells" is the currency in the game). Alison suspects that fish will sell for more money than sea creatures will, so she decides to conduct a hypothesis test at the a = 0.01 level with %3D %3D Họ: µ= 3,345 bells H1: p > 3,345 bells She finds a sample of 64 fish and computes their mean price to be 3,527 bells. a.
