1. Heart rates are determined before and 30 minutes after a Kettleball workout. It can be assumed that heart rates (bpm) are normally distributed. Use the data provided below to test to determine if average heart rates prior to the workout are significantly lower than 30 minutes after a Kettleball workout at the 0.10 level of significance. Let μ1μ1 = mean before workout.

before	69	60	62	72	73	77
after	77	63	70	74	74	85

Select the correct Hypotheses:

H0:μ1≥μ2H0:μ1≥μ2
Ha:μ1<μ2Ha:μ1<μ2

H0:μ1≤μ2H0:μ1≤μ2
Ha:μ1>μ2Ha:μ1>μ2

H0:μd≥0H0:μd≥0
Ha:μd<0Ha:μd<0

H0:μd≤0H0:μd≤0
Ha:μd>0Ha:μd>0

H0:μ1=μ2H0:μ1=μ2
Ha:μ1≠μ2Ha:μ1≠μ2

H0:μd=0H0:μd=0
Ha:μd≠0Ha:μd≠0

Test Statistic, t_test =
	[three decimal accuracy]

p-value =
	[three decimal accuracy]

Conclusion:

Fail to Reject H0H0
Reject H0H0

Interpret the conclusion in context:

There is not enough evidence to suggest the mean bpm before a Kettleball workout is lower than 30 minutes after the workout.
There is enough evidence to suggest the mean bpm before a Kettleball workout is lower than 30 minutes after the workout.

The count in a bacteria culture was 800 after 20 minutes and 1100 after 30 minutes. Assuming the count grows exponentially, What was the initial size of the culture? Find the doubling period. Find the population after 70 minutes. When will the population reach 10000. You may enter the exact value or round to 2 decimal places.

The old saying that you should wait at least 30 minutes after eating before you swim...

The old saying that you should wait at least 30 minutes after eating before you swim is based on the idea that after a big meal, blood will be diverted away from your arms and legs, towards your stomach’s digestive tract. And if your limbs don’t get enough blood flow to function, you’re at risk of drowning. With a reduced blood flow, there is potentially less oxygen available to the working muscle and stomach, which is a potential cause of...

HW 30 #3 Random samples of resting heart rates are taken from two groups. Population 1 exercises regularly, and Population 2 does not. The data from these two samples is given below: Population 1: 71, 63, 65, 70, 71, 67, 70 Population 2: 73, 71, 78, 73, 73, 77, 70, 69 Is there evidence, at an α=0.06 α = 0.06 level of significance, to conclude that there those who exercise regularly have lower resting heart rates? Carry out an appropriate...

A company of cables claims that a cable can stand an overload for 12 minutes before it blows. We want to test that by overloading 25cables with the same load. The average time the cables stand was 9.5minutes with a standard deviation of 2.5 minutes. Assume normality, do you tent to support of refute the claim?
