Question 16<>How much more time do statistics students spend studying for their final exam than they spend studying fortheir midterm exam? A researcher randomly selected ten statistics students and asked how many minutesthey spent studying for each exam. The results of the study are shown below.Time Studying for the Final and the Midterm150 306 236 220 319 162 159 184 153 25506 236FinalMidterm 86 128 165 165 76 119 57 182 126 33Assume both follow a Normal distribution.For this study, we should use Select an answerCompute the 90% confidence interval for the difference. Round to the nearest minute.Interpret the confidence interval in the context of the study:O With 90% confidence the population mean number of minutes statistics students spend studying fortheir final exam is between $52 and $149 more than the population mean number of minutesstatistics students spend studying for their midterm exam.O With 90% confidence the mean number of minutes that the ten sampled statistics students spentstudying for their final exam is between $52 and $149 more than the mean number of minutes thatthe ten sampled statistics students spent studying for their final exam.

The "Freshman 15" refers to the belief that college students gain 15 lb (or 6.8 kg) during their freshman year. Listed in the accompanying table are weights (kg) of randomly selected male college freshmen. The weights were measured in September and later in April. Use the listed paired sample data, and assume that the samples are simple random samples and that the differences have a distribution that is approximately normal. Complete parts (a) through (c).

Use a 0.01 significance level to test the claim that for the population of freshman male college students, the weights in September are less than the weights in the following April. In this example, Hd is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the April weight minus the September weight. What are the null and alternative hypotheses for the hypothesis test? Ho Hd 0 kg H₁ Hd > 0…
Researchers want to know if a tutoring program affects students’ ACT scores. They used a sample of twenty students and tested them before and after the tutoring program. Use Excel to perform a dependent sample t-test to determine whether the difference between the mean pretest score and the mean posttest score is significantly different. Assume unequal variance.
