Hi, Welcome and Thanks for using Just Answer

I am working on this and will post the answer as soon as ready.

Thanks.
Here they are ...

(a) Mean = 33.05, Median = 32, Mode = 32, Standard deviation = 14.18,

Q1 = 24.5, Q3 = 44, Min = 2, Max = 57

(b)Median = 32. This means the number of cardiograms done per day was

more than 32 half the time

Q1 = 24.5. This means the number of cardiograms done per day was

less than 25, quarter of the time

Q3 = 44. This means the number of cardiograms done per day was

more than 44, three-quarters of the time

I hope that helps. Please Rate My Answer (Tip If Happy).
