Question

Use the information in the following setting toanswer questions 1 - 7:

It has been reported that, during the prime mating season,female crickets are more

attracted to males that have high chirp rates. Generally,the average cricket chirps at a

rate around 60 per second. Use this value as the benchmarktest value. Chirp rates are

thought to be related to overall condition and the higherthe better. Eight mature male

crickets were placed on a high protein diet. After eightdays several attributes of the

calling behaviour of these crickets was assessed. One ofthe attributes was the chirp

rate (chirps/sec). The raw data for this attribute appearbelow in Table 1. Does this

data support the investigators’ claim that a highprotein diet is associated with higher call

rates? Let a = 0.025 and assume that thechirp rate data come from a normally

distributed population.
