A hypothesis test is done in which the alternative hypothesis is that more than 10% of a population is
left-handed. The p-value for the test is calculated to be 0.25.

If α=.05 which of the following statements is correct? Choose one.

(a) We cannot conclude that more than 10% of the population is left-handed
(b) We can conclude that exactly 25% of the population is left-handed
(c) We can conclude that more than 25% of the population is left-handed
(d) We can conclude that more than 10% of the population is left-handed

Option (a) We cannot conclude that more than 10% of the population is left-handed.

Step-by-step explanation:

We are given the following in the question:

Proportion of population that is left handed = 10% = 0.10

Significance level, α = 0.05

First, we design the null and the alternate hypothesis  

The null hypothesis sates that 10% of population is left handed and the alternate hypothesis state that more than 10% of the population is left handed.

This is a one tailed test.

The computed p-value is

P-value = 0.25

Comparison:

Since the p-value is greater than the significance level, we fail to reject the null hypothesis and accept the null hypothesis.

Thus, we conclude that 10% of the population is left handed.

Thus, the correct answer is

Option (a) We cannot conclude that more than 10% of the population is left-handed.

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!

49/6 is going to equal 8 1/6
