In the well-known Fletcher’s band-widening experiments, the bandwidth of noise centered on the frequency of a probe tone was increased. What was found? That the noise bandwidth was unrelated to masking That the amount of masking decreased with increasing bandwidth That he had to increase the level of the noise as its bandwidth increased That the wider the bandwidth, the more masking That the wider the bandwidth, the more masking but only up to a certain bandwidth What is the bandwidth after which there is no change in threshold referred to as?

The organization is planning a future experiment. They calculate that, with 80% power, 5% significance, and their anticipated sample size, the standardized minimum detectable effect is 0.14. If they believe the intervention increases contributions by 10% of the baseline mean, should the experiment be implemented as designed? Hint: you need to use the numbers in Savings Experiment Table 1.
