PLEASE HELP. YOU WILL BE MARKED BRAINLIEST IF ANSWER CORRECTLY :) Young Jedi Kelkin Soerre was in the middle of intense lightsaber training. So far she had blocked 34 laser blasts with her lightsaber out of 43 tries. How many consecutive laser blasts must she block successfully in order to raise her success rate to 84%? Round your answer to the nearest whole blast.

At wind speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. the cyclic nature of wind and moving sand determines the shape and location of large dunes. at a test site, the prevailing direction of the wind did not change noticeably. however, the velocity did change. fifty-nine wind speed readings gave an average velocity of x = 1075 cm/sec. based on long-term experience, σ can be assumed to be 245 cm/sec. (a) find a 95% confidence interval for the population mean wind speed at this site. (round your answers to the nearest whole number.) lower limit cm/sec upper limit cm/sec
