Scientists gathered data to test the research hypothesis that bees are more likely to sting a target

Question:

Scientists gathered data to test the research hypothesis that bees are more likely to sting a target that has already been stung by other bees. On eight separate occasions,they offered a pair of targets to a hive of angry bees;  one target in each pair had been previously stung, the other was pristine. On six of the eight occasions, the target that had been previously stung accumulated more new stingers.
a. Is the alternative hypothesis one-sided or two-sided?
b. Based on the sample size and distance between the null value and the observed proportion, estimate the strength of evidence: inconclusive, weak but suggestive, moderately strong, strong, or overwhelming.
c. Here are probabilities for the number of heads in eight tosses of a fair coin:

0 1 2 3 5 6 7 8 # Heads Probability 0.0039 0.0313 0.1094 0.2188 0.2734 0.2188 0.1094 0.0313 0.0039


Compute the p-value and state your conclusion.
