Homework Answers
The rock containing clinopyroxene and plagioclase (a type of feldspar) is called either basalt (fine grained extrusive rock) or gabbro (coarse grained intrusive rock). The plagioclase is generally calcium rich i.e. anorthite rich. But rock contains sodium rich feldspar. This means the sodium has replaced calcium. This replacement occurs in underwater (in oceans/seas) extrusion of basalt where sodium from seawater replaces the calcium in anorthite rich plagioclase feldspar. The altered basalt due to sodium exchange is called spillite which contains sodium rich feldspar and pyroxene.

A local fertility specialist noticed that some of her patients were heavy coffee drinkers. She wanted to know if there was any association between coffee drinking and conception in the first year of trying. She asked a random sample 40 patients (some of whom have successfully become pregnant) about coffee drinking. The table below summarizes the data (table entries represent raw frequencies of women in terms of pregnant or not and coffee drinker or not). Using alpha =.01, use the...

Section 1: Writing hypotheses 1. North River Health Clinic claims that the average waiting time for a patient is 20 minutes. A random sample of 6 patients showed a mean wait time of 23.2 minutes. At the.05 level of significance, does the sample show that the mean wait time is different from 20 minutes? State the null and alternate hypotheses. 2. North River Health Clinic claims that the average waiting time...

a large polling agency pays to have 40 valid polls
6. (4 pts) A large polling agency pays to have 40 valid polls conducted about a particular issue -- all with the same sample size and at the same confidence level. The chart on the right depicts the 40 confidence intervals, all drawn from the same population. 1 a. It appears that there were only 2 polls that were quite different from the others, in that neither of these contains...

Answer A and B for first question
A genetic experiment with peas resulted in one sample of offspring that consisted of 447 green peas and 164 yellow peas. a. Construct a 90% confidence interval to estimate of the percentage of yellow peas. b. It was expected that 25% of the offspring peas would be yellow. Given that the percentage of offspring yellow peas is not 25%, do the results contradict expectations? a. Construct a 90% confidence interval. Express the percentages...

/courses/1631958/q 2791378/take D Question 5 12 pts Pulse Rates of Men. A simple random sample of 40 men results in a standard deviation of 10.3 beats per minute (based on the data set provided). The normal range of pulse rates of adults is typically given as 60 to 100 beats per minute. If the range rule of thumb is applied to that normal range, the result is a standard deviation of 10 beats per minute. Use the sample results with...
