Please help me to understand this homework proble

The sample size is 17

	X = height	Y = peak flow rate
y (bar)	180.4118	660.0000
s	8.5591	117.9952
r = 0.32725
se = 115.1547

1. Give the appropriate mathematic null and alternative hypotheses she would use to see if height can predict respiratory health.

1. Calculate the standard error of the slope for the data above.

1. Calculate the appropriate test statistic.

1. Calculate the appropriate degrees of freedom.

1. Calculate the appropriate p-value.

1. Write a conclusive statement for this analysis ifa = 0.05.

Assume the researcher from the example above wished only to know if height and respiratory health were correlated with one another.

1. Give the appropriate mathematical null and hypotheses she would use to determine if height and peak flow rate were significantly correlated.

1. Calculate the slope for the fitted regression line from the data above.
