Using the pulse rate of females after they are partitioned into the three age brackets of 18-25, 26-40, and 41-80, we get the following Statdisk display. Using a 0.05 significance level, test the claim that females from the three age brackets have the same mean pulse rate. What do you conclude? Statdisk Source: DF: SS: MS: Test Stat, F: Critical F: P-Value: Treatment: 2 2280.049935 1140.024967 7.933788 3.058925 0.000539 Error: 144 20691.705167 143.692397 Total: 146 22971.755102

Step-by-step explanation:

Consider the given data of pulse rate and age of females

The null and alternative hypothesis is

: at least one of the mean is different from the others

The significance level is 0.05

The test statistic is F = 7.93

The Critical value is F = 3.06

Also, P-value is 0.0005

From the provided result it is clear that the P-value is less than the significance level , so researchers rejects the null hypothesis.

Therefore, the researcher conclude that there is sufficient evidence to rejection that the female from the three age bracket have the same mean pulse rate

On the basis of provided data , it is clear that the pulse rate of female affected by three age bracket

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
