State the conclusion.
O Ho is not rejected. There is sufficient evidence to indicate the level of concern after is dependent on the level of concern before.
O Ho is rejected. There is insufficient evidence to indicate the level of concern after is dependent on the level of concern before.
O Ho is not rejected. There is insufficient evidence to indicate the level of concern after is dependent on the level of concern before.
OH is rejected. There is sufficient evidence to indicate the level of concern after is dependent on the level of concern before.
Do the data suggest a change in "concern" after the general hospital experience? If so, describe the nature of the change.
OA small proportion of physicians appear to change their level of concern from high to low after general hospital experience.
A large proportion of physicians appear to change their level of concern from high to low after general hospital experience.
O A large proportion of physicians appear to change their level of concern from low to high after general hospital experience.
A small proportion of physicians appear to change their level of concern from low to high after general hospital experience.
The physicians' level of concern stayed the same after general hospital experience.
