16.25 The article "Effect of Storage Temperature on the Viability and Fertility of Bovine Sperm Diluted and Stored in Caprogen" (New Zealand Journal of Agricultural Research [1984]: 173-177) examined the ef- fect of temperature on sperm survival. Survival data for various storage times are given below. Use Friedman's test with a .05 significance level to determine if survival is related to storage temperature. Regard time as the blocking factor.
