telecommunications The marketing director of a service provider would like to gauge the market sentiment towards a new subscription plan which is yet to be launched. In a management meeting, it was decided that the subscription plan will be launched if more than 75% of the customers are in favour of this new plan. (a) To evaluate the plan, 350 customers were randomly selected and it is found that 284 were in favour of the new plan. At the 5% significance level, do the data provide sufficient evidence to support the launch of the plan? State Ho and H₁ and the test statistic. (b) The marketing director decided to segment the customers based on their monthly data usage. The customers in the sample are divided into two categories: heavy users and light users. It is found that 20 of the 200 in the heavy users category were in favour of the new plan and 10 of the 150 in the light users category were in favour of the new plan. At the 5% significance level, do the data provide sufficient evidence to conclude that more heavy users are in favour of the new subscription plan? State Ho and H₁ and the test statistic.
