Answer:
20 grape lollipops
Step-by-step explanation:
From the 30 lollipops, 6 were grape
P(grape) = grape/total
=6/30
=1/5
If we get 100 lollipop, to determine the number that would be grape, we multiply the number of lollipops by the probability that they are grape
grape = number * probability
= 100 * 1/5
=20

Answer:
28 + 2/10 + 4/100
Step-by-step explanation:
28.24
28 ones plus 2 tenths plus 4 hundredths
28 + 2/10 + 4/100
4x10=40
1/2 x 3 x 6= 9
9x40=360
Answer:
(c) H0 should be rejected
Step-by-step explanation:
Null hypothesis (H0): population mean is equal to 5
Alternate hypothesis (Ha): population mean is greater than 5
Z = (sample mean - population mean) ÷ (sd/√n)
sample mean = 5.3, population mean = 5, sd = 1, n = 500
Z = (5.3 - 5) ÷ (1/√500) = 0.3 ÷ 0.045 = 6.67
Using the normal distribution table, for a one tailed test at 0.01 significance level, the critical value is 2.326
Conclusion:
Since 6.67 is greater than 2.326, reject the null hypothesis (H0)
