Answer:
97% confidence interval for the survey is between a lower limit of 0.45 and an upper limit of 0.67
Step-by-step explanation:
Confidence Interval is given by the mean + or - error margin

Answer: 45
=====================================================
Work Shown:
n = number of rolls = 150
p = probability of rolling a "1" = 0.3
n*p = expected number of "1"s that show up out of the 150 rolls
n*p = 150*0.3
n*p = 45
We expect about 45 ones will show up.
