Arriane has geese on her farm. She claims the meah weight of eg less than the mean weight of eggs from her white geese. She recorded the weights of eggs, in grams, from a random selec shown in the table. Weights of eggs from black geese 136 134 142 Weights of eggs from white geese 135 138 141 In order to test her claim, Arriane performs a /-test at a 10% level that the weights of eggs are normally distributed and the samples (a) State, in words, the null hypothesis. (b) Calculate the p-value for this test. (c) State whether the result of the test supports Arriane's claim.

Hellen has just started a new years competition for her local climbing gym. There are two categories for this competition: singles and group (18 people). The rules are simple, put in the most hours in one months time and you get a guided tour to climb Ten Sleep canyon. She knows from running this competition over the years that the number of hours climbers at her gym spend training during this competiton is approximately normal and their mean competition hours per month in the gym are 24 hrs with a standard devaition of 6 hrs. Singles Distribution: X~N( , ) Group Distribution: x̄~N( , ) The winning single participant last year was in the 97 th percentile.... how many hours did the winner accumulate over the month?   One of Hellan's friends Dave put in 27.12 hours on the wall. What is the probablity that another individual will beat his time?   If someone puts in between 25.5-32.1 hours on the wall they get a Mountain Goat shirt. What percent of the singles competitors is expected to…

According to data from the Tobacco Institute Testing Laboratory, a certain brand of cigarette contains an average of 1.4 milligrams of nicotine. An advocacy group questions this figure, and commissions an independent test to see if the the mean nicotine content is higher than the industry laboratory claims. The test involved randomly selecting n = 15 cigarettes, measuring the nicotine content (in milligrams) of each cigarette. The data is given below: 1.8, 1.8, 1.5, 1.1, 1.4, 1.3, 1.3, 1.4, 1.1, 1.3, 1.6, 1.2, 1.8, 1.4, 1.6; Download .csv file Not sure how to perform some of the tasks with R-Studio?

researchers wanted to determine if carpeted rooms contained more baterica than uncapted rooms. to determine the amount of bacterica in a room reseachers pumpled the air from the room over a petri dish at the rate of 1 cubic foot per minute for eight carpeted rooms and eight uncaprted rooms. colonies of baterica were alled to form in 16 petri dishes. the results shown below are the baterica counta per cubic foot   mean standard deviation  sample size    capeted room  11.2 2.6774 8   uncapted room  9.7875 3.21 8   you want ti test using sigificance level of 0.01 whether the mean bactiria count is high for carpeted rooms than for uncapteed rooms. test whether the mean bacteria count is high for carpeted rooms thatn uncarpeted rooms. show all steps using the p value method.   what is Ho and H1? what is the test statsic and p value? what conclusion can be made?

In California, we need more rain to sustain the health of our natural environment, argriculture, and economic. A group of statistics students in Oxnard College recorded the amount of rain during 2016-2017 school year, measuring the intensity by the inches of rain, and the results were: Inches of Rain 1 2 3 4 5 6 Frequency 4 1 2 4 4 4 The mean (¯xx¯) rain intensity:  inches (Please show your answer to 1 decimal place.)The median rain intensity:  inchesThe mode rain intensity:  inches (Please separate your answers by ',' in the bimodal situation. Enter DNE if there is no mode or if there are more than two modes.)
