At a nearby frozen yogurt shop, the mean cost of a pint of frozen yogurt is $1.50 with a standard deviation of $0.10. Assuming the data is normally distributed, approximately what percent of customers are willing to pay between $1.30 and $1.70 for a pint of frozen yogurt? a) 99.7%.
b) 95%.
c) 34%.
d) 68%.

i think its b or c ill give you the steps in a min

Step-by-step explanation:

95%

Step-by-step explanation:

Since we know that the mean is 1.50 and the standard deviation is 0.10, we can note that both 1.30 and 1.70 are two standard deviation (2*0.10 = 0.20) away from 1.50. Assuming the data is normal, it should contain 95% of the data.
