The total will be 08.99 because that’s how you divide and he is winning
1500 total surveys sent
Returned: 245 + 173 + 185 + 92 = 695
1500-695 = 805
250*0.62= 155
155 pounds is your answer.
It would be 0 till the end of the month because that’s where it started from and when it’s going to end
Answer:
95%
Step-by-step explanation:
About 95% of the area is within two standard deviation in standard normal distribution. This can be explained by finding the probability within 2 standard deviation using standard normal distribution.
P(z1<Z<z2)=P(-2<Z<2)
P(-2<Z<2)=P(-2<Z<0)+P(0<Z<2)
P(-2<Z<2)=0.4772+0.4772
P(-2<Z<2)=0.9544
Thus, About 95% of the area is between z2 and z2
