a) Null and alternative hypothesis:
b) A Type I error is made when a true null hypothesis is rejected. In this case, it would mean a conclusion that the proportion is significantly bigger than 10%, when in fact it is not.
c) The consequences would be that they would be more optimistic than they should about the result of the investment, expecting a proportion of students that is bigger than the true population proportion.
d) A Type II error is made when a false null hypothesis is failed to be rejected. This would mean that, although the proportion is significantly bigger than 10%, there is no enough evidence and it is concluded erroneously that the proportion is not significantly bigger than 10%
e) The consequences would be that the investment may not be made, even when the results would have been more positive than expected from the conclusion of the hypothesis test.
Step-by-step explanation:
a) The hypothesis should be carried to test if the proportion of students that would eat there at least once a week is significantly higher than 10%.

Answer:
Mike can stitch one shirt in 6 hours and in 1 hour he can stitch (0.167) shirts.
Step-by-step explanation:
Mike can stitch 7 shirts in 42 hours

Now we calculate the work done in one hour.
He can stitch in 1 hour = shirts or 0.167 shirts
Mike can stitch one shirt in 6 hours and in 1 hour he can stitch shirts.
