Answer:
0.1052
Step-by-step explanation:
Given that proportion of germination in the population is 94% =0.94
p = 0.96
Sample size = 220
Std dev of p = 
The probability that more than 96% of the 220 seeds in the packet will germinate
= 
Assumptions are np and nq >5 and also sample size >220 hence normal
Divide total price by quantity:
15.60 / 6 = 2.60
Unit price = $2.60
67.27
155 = 1.55 x 43.4 = 67.27
